[dpdk-dev] [PATCH] net/i40e: fix VF testpmd startup failure issue

[Xiaoyun Li]

New testpmd will get CRC strip offload from rx_offload_capa. I40evf cannot
disable CRC strip. And in fact, it is enabled by PF. This patch solves the
issue by adding CRC strip flag into rx_offload_capa in i40e and i40evf.

Fixes: 8b9bd0efe0b6 ("app/testpmd: disable Rx VLAN offloads by default")
