I found some places, that erroneously return the value obtained from the copy_to_user() call: if some amount of bytes were not able to get to the user (this is what this one returns) the proper behavior is to return the -EFAULT error, not that number itself. Signed-off-by:

In commit ba749ae9 ([XFRM]: alg_key_len should be unsigned to avoid integer divides <http://git2.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=commitdiff;h=ba749ae98d5aa9d2ce9a7facde0deed454f92230>) alg_key_len field of struct xfrm_algo was converted to unsigned int to avoid integer divides. Then Herbert in commit 1a6509d9 ([IPSEC]: Add support for combined mode algorithms) added a new structure xfrm_algo_aead, that resurrected a signed int for alg_key_len and re-introduce integer divides. This patch avoids these divides and saves 64 bytes of text on i386. Signed-off-by:

- vlans were using a single CAM register (see mac_set_vlan_cam) - setting the address filtering registers for vlans is not needed when there is no vlan The non-tagged interface is filtered out as soon as a tagged (!= 0) interface is created. Its traffic appears again when an zero-tagged interface is created. Tested on Via Epia SN (VT6130 chipset) with several vlans whose tag was above or beyond 255. Signed-off-by:

This patch fixes an issue seen with the realtek 8201 phy. This phy has a problem with crossover detection and it needs to be disabled. The problem only arises on certain switches. Therefore, a module parameter has been added to allow enabling crossover detection if needed. The default will be set to disabled. Signed-off-by:

gianfar was unable to handle failed skb allocation for rx buffers, so we were spinning until it succeeded. Actually, it was worse--we were spinning for a long time, and then silently failing. Instead, we take Stephen Hemminger's suggestion to try the allocation earlier, and drop the packet if it failed. We also make a couple of tweaks to how buffer descriptors are set up. Signed-off-by:

Since 43cc71ee, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable network platform drivers, to re-enable auto loading. NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support. That looks problematic in the first place (it even uses the ancient "struct device_driver" binding scheme for platform_bus!) and I suspect it will vanish soonish when arch/powerpc rules the world. Also, drivers/net/ne.c would have needed more thought to sort out. [akpm@linux-foundation.org: fix sgiseeq.c] [dbrownell@users.sourceforge.net: more drivers, registration fixes] Signed-off-by:

This patch adds support for a new backoff algorithm for half duplex supported in newer hardware. The old method is will be designated as legacy mode. Re-seeding random values for the backoff algorithms are performed when a transmit has failed due to a maximum retry count (1 to 15, where max is considered the wraparound case of 0). Signed-off-by:

Sometimes the specific interaction between the platform and the PHY requires special handling. For instance, to change where the PHY's clock input is, or to add a delay to account for latency issues in the data path. We add a mechanism for registering a callback with the PHY Lib to be called on matching PHYs when they are brought up, or reset. Signed-off-by:

While trying to fix http://bugzilla.kernel.org/show_bug.cgi?id=8952 I looked at a few other drivers to figure out what drivers _should_ be doing for suspend/resume. I noticed typhoon driver is likely doing more than it needs to. Patch below is untested since I don't have the HW. Suspend/resume code across NIC drivers is fairly inconsistent. And I couldn't find any documentation on what the canonical sequence NICs need to do for suspend or resume. Is there any? Barring contrary advice, I'm going model the tulip suspend/resume fixes after tg3.c since a number of "modern" (< 5 years old) laptops have that and I'm silly enough to assume it works.

This patch adds ibm_newemac PHY clock workaround for 440EP/440GR EMAC attached to a PHY which doesn't generate RX clock if there is no link. The code is based on the previous ibm_emac driver stuff. The 440EP/440GR allows controlling each EMAC clock separately as opposed to global clock selection for 440GX. BenH: Made that #ifdef CONFIG_PPC_DCR_NATIVE for now as dcri_* stuff doesn't exist for MMIO type DCRs like Cell. Some future rework & improvements of the DCR infrastructure will make that cleaner but for now, this makes it work. Signed-off-by:

The PowerPC 440GX Taishan board fails to reset EMAC3 (reset timeout error) if there's no link. Because of that it fails to find PHY chip. The older ibm_emac driver had a workaround for that: the EMAC_CLK_INTERNAL/EMAC_CLK_EXTERNAL macros, which toggle the Ethernet Clock Select bit in the SDR0_MFR register. This patch does the same for "ibm,emac-440gx" compatible chips. The workaround forces clock on -all- EMACs, so we select clock under global emac_phy_map_lock.

Convert ibm_newemac to use the of_device_is_available function when checking for unused/unwired EMACs. We leave the current check for an "unused" property to maintain backwards compatibility for older device trees. Newer device trees should simply use the standard "status" property in the EMAC node.

On some 4xx PPC's (e.g. 460EX/GT), the rx channel number is a multiple of 8 (e.g. 8 for EMAC1, 16 for EMAC2), but enabling in MAL_RXCASR needs the divided by 8 value for the bitmask. Signed-off-by:

Several components to this complex fix. The es2lan cards occasionally gave a "HW Error" especially when forcing speed. Some users also reported that the BMC stole ARP packets. The fixes include setting the proper SW_FW bits to tell the BMC that we're active and not do any un-initialization at all, so the setup routine is largely changed. Signed-off-by:

The ethtool -c / -C interface can now be used to modify the irq moderation algorithm. This change does not require an adapter reset and can thus be used at all times. The adapter only supports changing/reading rx-usecs which has special values for 0, 1 and 3: 0 - no irq moderation whatsoever 1 - normal moderation favoring regular mixed traffic (default) 3 - best attempt at low latency possible at cost of CPU For values between 10 and 10000 the rx-usecs defines "the minimum time between successive irqs" in usec, unlike the module parameter.

Several stats registers are completely unused and we just waste pci bus time reading them. We also omit using the high 32 bits of the GORC/ GOTC counters. We can just read clear them and only read the low registers. Mii-tool can also break es2lan if it executes a MII PHY register ioctl while the device is in autonegotiation. Unfortunately it seems that several applications and installations still perform this ioctl call periodically and especially in this crucial startup time. We can fool the ioctl by providing fail safe information that mimics the "down" link state and only perform the dangerous PHY reads once after link comes up to fill in the real values. As long as link stays up the information will not change. Signed-off-by:
