Subject: net/sfc: check ID overflow in action port ID
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fb3c4efb65be520082a34c0afb85d492ff093c82;p=dpdk.git

net/sfc: check ID overflow in action port ID

The container in the action configuration is U32,
but the ID is U16, and overflow check is missing.

Fixes: 1fb65e4dae8a ("net/sfc: support flow action port ID in transfer rules")
