[dpdk-dev] [PATCH] app/testpmd: enable CRC strip without capability check

[Ferruh Yigit]

Some hardware doesn't support disabling CRC strip. In techboard it has
been decided to enable CRC strip always.

The testpmd update in commit 8b9bd0efe0b6, enables CRC strip only if
PMD reports CRC strip capability. Not all PMDs updated to report CRC
strip.

For the PMDs not reporting CRC strip testpmd behavior changed and
disabling CRC strip for them. And this may generate error for PMDs that
doesn't support disabling CRC strip.

Removing capability check for this release. In long term there can be
option to remove CRC strip flag completely or adding a new flag to let
PMD say disabling is not supported.

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