The patch which fixed gianfar so it drops packets when it runs out of memory left in the code which frees the skb when it drops packets. Change the code so that we only free the skb if the new skb was successfully created. Signed-off-by:

In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by:

genphy_setup_forced hasn't actually reset the PHY for a long time, but a comment to that effect remained in the code, so code continued to act as if it *had* reset the PHY, and called the necessary fixup functions to respond to a PHY reset. With no reset, those functions are no longer needed, so we remove them. Signed-off-by:

Whenever we want to update the status field in a BD, we usually want to update the length field, too. By combining them into one 32-bit field, we reduce the number of stores to memory shared with the controller, and we eliminate the need for order-enforcement, as the length and "READY" bit are now updated atomically at the same time.

This code is based strongly on code from Dai Haruki <Dai.Haruki@freescale.com>. The gianfar Buffer Descriptors are arranged in a circular array, the end of which is denoted by setting the "WRAP" bit in the descriptor. However, the software knows the end of the ring because it knows how many descriptors are there. Rather than check each descriptor for whether the WRAP bit is set, use pointer math to determine where the next BD is. This is also useful for when we want to look at BDs other than the very next one (for Scatter-Gather). Signed-off-by:

The eTSEC can prepend up to 32 bytes to a received frame, usually for the purpose of aligning the IP address to a word boundary, so this turns it on. While we're in there, make the handling of the pre-frame bytes (padding and Frame Control Block) cleaner. Signed-off-by:

Fix some bugs in the ethtool configuration functions: * gfar_clean_rx_ring should not be called with interrupts disabled. * Update last transmission time to avoid tx timeout. * Delete redundant NETIF_F_IP_CSUM check in gfar_start_xmit * Use netif_tx_lock_bh when reconfiguring the tx csum Signed-off-by:

Store the interrupt coalescing values in the form in which they will be written to the interrupt coalescing registers. This puts a little overhead into the ethtool configuration, and takes it out of the interrupt handler Signed-off-by:

Does the same for the accompanying MDIO driver, and then modifies the TBI configuration method. The old way used fields in einfo, which no longer exists. The new way is to create an MDIO device-tree node for each instance of gianfar, and create a tbi-handle property to associate ethernet controllers with the TBI PHYs they are connected to.

1.When no interface is specified in an IPV6_PKTINFO ancillary data item, the interface specified in an IPV6_PKTINFO sticky optionis is used. RFC3542: 6.7. Summary of Outgoing Interface Selection This document and [RFC-3493] specify various methods that affect the selection of the packet's outgoing interface. This subsection summarizes the ordering among those in order to ensure deterministic behavior. For a given outgoing packet on a given socket, the outgoing interface is determined in the following order: 1. if an interface is specified in an IPV6_PKTINFO ancillary data item, the interface is used. 2. otherwise, if an interface is specified in an IPV6_PKTINFO sticky option, the interface is used.

When get receiving interface index while no message is received, the the value seted with setsockopt() should be returned. RFC 3542: Issuing getsockopt() for the above options will return the sticky option value i.e., the value set with setsockopt(). If no sticky option value has been set getsockopt() will return the following values: - For the IPV6_PKTINFO option, it will return an in6_pktinfo structure with ipi6_addr being in6addr_any and ipi6_ifindex being zero.

RFC 3542: Issuing getsockopt() for the above options will return the sticky option value i.e., the value set with setsockopt(). If no sticky option value has been set getsockopt() will return the following values: 3.Make the setsockopt implementation POSIX compliant. Signed-off-by:

These 4 drivers have identical full duplex flow control resolution functions. This patch changes them all to use one common function. The function in question decides whether a device should enable TX and RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this should also be useful for other drivers. Signed-off-by:

flags used within drivers for indicating tx and rx flow control are defined in 4 drivers (and probably more), move these constants to mii.h. The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3. Signed-off-by:

The enc28j60 driver reads incoming packets in the process (workqueue) context, not in a tasklet or the interrupt context. Thus, we should use netif_rx_ni() to deliver those packets to the networking layer, instead of netif_rx(). This way incoming packets don't wait in the incoming queue for the next IRQ to be serviced.
