linux-stable.git/include/linux/inet_lro.h, branch linux-2.6.25.y Linux kernel stable tree [LRO]: fix lro_gen_skb() alignment 2007-12-05T13:37:32+00:00 Andrew Gallatin gallatin@myri.com 2007-12-05T10:31:42+00:00 621544eb8c3beaa859c75850f816dd9b056a00a3 Add a field to the lro_mgr struct so that drivers can specify how much padding is required to align layer 3 headers when a packet is copied into a freshly allocated skb by inet_lro.c:lro_gen_skb(). Without padding, skbs generated by LRO will cause alignment warnings on architectures which require strict alignment (seen on sparc64). Myri10GE is updated to use this field.

[NET]: Generic Large Receive Offload for TCP traffic 2007-10-10T23:47:46+00:00 Jan-Bernd Themann themann@de.ibm.com 2007-08-09T05:38:05+00:00 71c87e0cedca843162206c698cfa02e5fea9e2e3 This patch provides generic Large Receive Offload (LRO) functionality for IPv4/TCP traffic. LRO combines received tcp packets to a single larger tcp packet and passes them then to the network stack in order to increase performance (throughput). The interface supports two modes: Drivers can either pass SKBs or fragment lists to the LRO engine. Signed-off-by: Jan-Bernd Themann <themann@de.ibm.com> Signed-off-by: David S.
