Hi, I just looked at stable/10 and found the following 4 drivers have set the if_hw_tsomax, if_hw_tsomaxsegcount and if_hw_tsomaxsegsize fields: ./xen/netfront/netfront.c ./cxgbe/t4_main.c ./oce/oce_if.c ./vmware/vmxnet3/if_vmx.c If you are the author/maintainer for a network device driver that does TSO and is not on the above list...please, please fill in the above fields before the call to ether_ifattach(), so that TSO will hopefully work correctly with NFS/iSCSI. (I said "hopefully" because there might be other bugs related to TSO in your driver that I wouldn't know about.) Maybe someone could mention this at BSDCan too? Thanks in advance for doing this, rick ps: I would be really nice to get this done for 10.2 imho.
