* net/inet_lro: remove setting skb->ip_summed when not LRO-ableEli Cohen2008-06-27
| | | | | | | | | | | | | | When an SKB cannot be chained to a session, the current code attempts to "restore" its ip_summed field from lro_mgr->ip_summed. However, lro_mgr->ip_summed does not hold the original value; in fact, we'd better not touch skb->ip_summed since it is not modified by the code in the path leading to a failure to chain it. Also use a cleaer comment to the describe the ip_summed field of struct net_lro_mgr.

* [LRO] Fix lro_mgr->features checksBrice Goglin2008-01-09
| | | | | | | | | | lro_mgr->features contains a bitmask of LRO_F_* values which are defined as power of two, not as bit indexes. They must be checked with x&LRO_F_FOO, not with test_bit(LRO_F_FOO,&x). Signed-off-by: Brice Goglin <Brice.Goglin@inria.fr> Acked-by: Andrew Gallatin <gallatin@myri.com> Signed-off-by: David S.

* [LRO]: fix lro_gen_skb() alignmentAndrew Gallatin2007-12-05
| | | | | | | | | | | | | 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.

* fix endianness bug in inet_lroAl Viro2007-10-14
| | | | | | | | | all uses of and almost all assignments to lro_desc->tcp_ack assume that it's net-endian; one converts net-endian to host-endian and sticks it in lro_desc->tcp_ack. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* [NET]: sparse warning fixesStephen Hemminger2007-10-10
| | | | | | | | | Fix a bunch of sparse warnings. Mostly about 0 used as NULL pointer, and shadowed variable declarations. One notable case was that hash size should have been unsigned.

* [NET]: Generic Large Receive Offload for TCP trafficJan-Bernd Themann2007-10-10
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.
