Subject: net/mvpp2: fix frame size checking
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1c9a958a8bfb7cb4e2082b97d01849d4ba91c13b;p=dpdk.git

net/mvpp2: fix frame size checking

Need to add CRC len to the frame-size to compare against
max_rx_pkt_len which includes it.

Fixes: 79ec62028b9a ("net/mvpp2: update MTU and MRU related calculations")
