2010-12-17qlcnic: reset pci function unconditionally during probeRajesh Borundia2-6/+3
Some boot code drivers dont have cleanup routine, so pci function remains in unknown state prior to driver load. So during driver load issue FLR unconditionally. Update driver version to 5.0.14.

2010-12-16net: Fix drivers advertising HW_CSUM feature to use csum_startMichał Mirosław14-15/+15
Some drivers are using skb_transport_offset(skb) instead of skb->csum_start for NETIF_F_HW_CSUM offload. This does not matter now, but if someone implements checksumming of encapsulated packets then this will break silently. TSO output paths are left as they are, since they are for IP+TCP only (might be worth converting though). Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.

2010-12-16tcp: relax tcp_paws_check()Eric Dumazet1-1/+7
Some windows versions have wrong RFC1323 implementations, with SYN and SYNACKS messages containing zero tcp timestamps. We relaxed in commit fc1ad92dfc4e363 the passive connection case (Windows connects to a linux machine), but the reverse case (linux connects to a Windows machine) has an analogue problem when tsvals from windows machine are 'negative' (high order bit set) : PAWS triggers and we drops incoming messages. Fix this by making zero ts_recent value special, allowing frame to be processed.

2010-12-14net: Abstract default MTU metric calculation behind an accessor.David S. Miller6-39/+60
Like RTAX_ADVMSS, make the default calculation go through a dst_ops method rather than caching the computation in the routing cache entries. Now dst metrics are pretty much left as-is when new entries are created, thus optimizing metric sharing becomes a real possibility. Signed-off-by: David S. Miller <davem@davemloft.net>

2010-12-13net: Abstract default ADVMSS behind an accessor.David S. Miller11-33/+75
Make all RTAX_ADVMSS metric accesses go through a new helper function, dst_metric_advmss(). Leave the actual default metric as "zero" in the real metric slot, and compute the actual default value dynamically via a new dst_ops AF specific callback. For stacked IPSEC routes, we use the advmss of the path which preserves existing behavior. Unlike ipv4/ipv6, DecNET ties the advmss to the mtu and thus updates advmss on pmtu updates. This inconsistency in advmss handling results in more raw metric accesses than I wish we ended up with. Signed-off-by: David S. Miller <davem@davemloft.net>
