In RHEL 5.5 and above, a NIC driver must explicitly set the NETIF_F_VLAN_TSO flag to enable TCP Segment Offload(TSO)/Large Segment Offload(LSO). In RHEL 5 kernels previous to RHEL 5.5 this was not needed. This patch explicitly sets that flag.

Adding Gospo to this on cc: probably would like to review this at some point on rhkl anyway...
I have not looked at the patches, but how does this address the problems highlighted in bug 600350?
(In reply to comment #4) > I have not looked at the patches, but how does this address the problems > highlighted in bug 600350? Andy, these patches are actually for the qlcnic driver which is a new driver in RHEL 5.6. The qlcnic driver covers the to be released QLogic 82XX CNAs. The driver involved in 600350 is qlge which is for QLogic's previous generation CNAs, the 81XX series.
