> Subject: [PATCH] app/testpmd: enable CRC strip without capability check
> 
> 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")
