Return notify intr credits after notify intr from firmware. This is especially important for legacy PCI intr mode, where not returning credits would cause PBA to remain asserted which would get us right back into the ISR. Signed-off-by:

We're supposed to drop it at the bridge. However, because the check was placed in br_forward instead of __br_forward, it's only effective if we are sending the packet through a single port. This patch fixes it by moving the check into __br_forward. Signed-off-by:

Ira Snyder found that commit 8c7396ae "gianfar: Merge Tx and Rx interrupt for scheduling clean up ring" can cause hangs. It's because there was removed clearing of interrupts in gfar_schedule_cleanup() (which is called by an interrupt handler) in case when netif scheduling has been disabled. This patch brings back this action and a comment. Reported-by:

This patch removes connection tracking handling for ICMPv6 messages related to Stateless Address Autoconfiguration, MLD, and MLDv2. They can not be tracked because they are massively using multicast (on pre-defined address). But they are not invalid and should not be detected as such. Signed-off-by:

The patch fixes a typo in the inverse mapping of Node Information request. Following draft-ietf-ipngwg-icmp-name-lookups-09, "Querier" sends a type 139 (ICMPV6_NI_QUERY) packet to "Responder" which answer with a type 140 (ICMPV6_NI_REPLY) packet. Signed-off-by:

gro: Optimise TCP packet reception As this function can be called more than half a million times for 10GbE, it's important to optimise it as much as we can. This patch uses bit ops to logical ops, as well as open coding memcmp to exploit alignment properties. Signed-off-by:

As this function can be called more than half a million times for 10GbE, it's important to optimise it as much as we can. This patch does some obvious changes to use 2-byte and 4-byte operations instead of byte-oriented ones where possible. Bit ops are also used to replace logical ops to reduce branching. Signed-off-by:

This patch optimises the Ethernet header comparison to use 2-byte and 4-byte xors instead of memcmp. In order to facilitate this, the actual comparison is now carried out by the callers of the shared dev_gro_receive function. This has a significant impact when receiving 1500B packets through 10GbE.

This patch prepares for the move of the same_flow checks out of dev_gro_receive. As such we need to remember the number of held packets since doing a loop just to count them every time is silly. Signed-off-by:

Several devices need to insert some "pre headers" in front of the main packet data when they transmit a packet. Currently we allocate only 16 bytes of pad room and this ends up not being enough for some types of hardware (NIU, usb-net, s390 qeth, etc.) So increase this to 32. Note that drivers still need to check in their transmit routine whether enough headroom exists, and if not use skb_realloc_headroom(). Tunneling, IPSEC, and other encapsulation methods can cause the padding area to be used up. Signed-off-by: -

Tap devices can make use of a small MAC filter set via the TUNSETTXFILTER ioctl. The filter has a set of exact matches plus a hash for imperfect filtering of additional multicast addresses. The current code is unbalanced, adding unicast addresses to the multicast hash, but only checking the hash against multicast addresses. This results in the filter dropping unicast addresses that overflow the exact filter. The fix is simply to disable the filter by leaving count set to zero if we find non-multicast addresses after the exact match table is filled. Signed-off-by:

This patch addresses two minor items I found while cleaning up the igb driver for our sourceforge version. The first clears the context index if we don't flag that we need it. The second item is that eims_other should be used instead of bit defines when setting all of the EICS bits prior to reset. Signed-off-by:

It was seen with repeated interface up/down testing that there was a large stray between the stats reported by the queues and the stats reported by the HW. It was found to be an issue in that hw stats were being reset without first being recorded. This change records the stats before wiping them from the system via the reset. Signed-off-by:
