[dpdk-dev] [PATCH] vmxnet3: fix txq flags check

[Yong Wang]

Now that vmxnet3 supports TCP/UDP checksum offload, let's update
the default txq flags to allow such offloads.  Also fixed the tx
queue setup check to allow TCP/UDP checksum and only error out
if SCTP checksum is requested.

Fixes: f598fd063bb1 ("vmxnet3: add Tx L4 checksum offload")
