Hi, IBM EMAC driver performs device reset (drivers/net/ibm_newemac/core.c: emac_probe() -> emac_init_phy() -> emac_reset()) before registering appropriate net_device (emac_probe() -> register_netdev()), so net_device name contains raw format string during EMAC reset ("eth%d"). If the case of reset timeout, emac_report_timeout_error() function is called to report an error. The problem is this function uses net_device name to report device related, which is not correct, as a result in the kernel log buffer we see: eth%d: reset timeout The solution is to print device_node full_name instead. After applying the patch proposed, error string is like the following: /plb/opb/ethernet@ef600e00: reset timeout Signed-off-by: Mikhail Zolotaryov <lebon@lebon.org.ua> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David S.

There is no gain using prefetch() in dev_hard_start_xmit(), since we already had to read ops->ndo_select_queue pointer in dev_pick_tx(), and both pointers are probably located in the same cache line. This prefetch call slows down fast path because of a stall in address computation. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

A zero length frame filter was recently introduced in ROSE protocole. Previous commit makes the same at AX25 protocole level. This patch has the same purpose for NetRom protocole.

commit 1577ecef ("netdev: Merge UCC and gianfar MDIO bus drivers") broke the TSEC TBI PHY support: the driver now refuses to probe TBI MDIO buses as it doesn't know about "fsl,gianfar-tbi" compatible entry, and thus _probe() fails with -ENODEV status. Fix this by adding "fsl,gianfar-tbi" to the list of known Gianfar MDIO buses.

dev_queue_xmit() needs to dirty fields "state", "q", "bstats" and "qstats" On x86_64 arch, they currently span three cache lines, involving more cache line ping pongs than necessary, making longer holding of queue spinlock. We can reduce this to one cache line, by grouping all read-mostly fields at the beginning of structure. (Or should I say, all highly modified fields at the end :) ) Before patch : offsetof(struct Qdisc, state)=0x38 offsetof(struct Qdisc, q)=0x48 offsetof(struct Qdisc, bstats)=0x80 offsetof(struct Qdisc, qstats)=0x90 sizeof(struct Qdisc)=0xc8 After patch : offsetof(struct Qdisc, state)=0x80 offsetof(struct Qdisc, q)=0x88 offsetof(struct Qdisc, bstats)=0xa0 offsetof(struct Qdisc, qstats)=0xac sizeof(struct Qdisc)=0xc0 Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

The watchdog will schedule an interrupt to help make sure queues are cleaned in the case when an interrupt is missed, most likely due to very high load. On 82599, there are extra interrupt registers to account for the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for 82598). These must be taken into account when performing this operation in the watchdog.

82598's PCI bus reporting on driver load was broken after 82599 merged.

As with igb, when the e1000e driver is fed 802.1q packets with hardware checksum on, it chokes with an error of the form: checksum_partial proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out wiht the correct hardware checksum. Thanks to Kand Ly <kand@riverbed.com> for discovering the issue and the coming up with a solution.

The cpu_to_le16 here looks suspicious to me, I don't think we need it because put_unaligned_le16 also does this.

This patch replaces the generic eth_mac_addr function with one that also updates the hardware mac address registers. It also renames the existing smsc911x_set_mac_address function to smsc911x_hw_set_mac_address for clarity. Newer LAN911x and all LAN921x devices also support changing the mac address while the device is running, which is useful for some bonding modes.

smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.
