Add a simple test for TSO. Send a few MB of data and check device stats to verify that the device was performing segmentation. Do the same thing over a few tunnel types. Injecting GSO packets directly would give us more ability to test corner cases, but perhaps starting simple is good enough? # ./ksft-net-drv/drivers/net/hw/tso.py # Detected qstat for LSO wire-packets KTAP version 1 1..14 ok 1 tso.ipv4 # SKIP Test requires IPv4 connectivity ok 2 tso.vxlan4_ipv4 # SKIP Test requires IPv4 connectivity ok 3 tso.vxlan6_ipv4 # SKIP Test requires IPv4 connectivity ok 4 tso.vxlan_csum4_ipv4 # SKIP Test requires IPv4 connectivity ok 5 tso.vxlan_csum6_ipv4 # SKIP Test requires IPv4 connectivity ok 6 tso.gre4_ipv4 # SKIP Test requires IPv4 connectivity ok 7 tso.gre6_ipv4 # SKIP Test requires IPv4 connectivity ok 8 tso.ipv6 ok 9 tso.vxlan4_ipv6 ok 10 tso.vxlan6_ipv6 ok 11 tso.vxlan_csum4_ipv6 ok 12 tso.vxlan_csum6_ipv6 # Testing with mangleid enabled ok 13 tso.gre4_ipv6 ok 14 tso.gre6_ipv6 # Totals: pass:7 fail:0 xfail:0 xpass:0 skip:7 error:0 Note that the test currently depends on the driver reporting the LSO count via qstat, which appears to be relatively rare (virtio, cisco/enic, sfc/efc; but virtio needs host support).
