Subject: net/mlx4: add CRC stripping capability
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0ab56bd30c74cbd36758bc92cbce65c4a6988c1b;p=dpdk.git

net/mlx4: add CRC stripping capability

This patch updates mlx4 Rx offload capabilities to also indicate that
Rx CRC stripping is (always) supported.

Since the device does not support disabling CRC stripping the PMD
silently ignores such requests.
