Subject: RDMA/cma: Update cma_validate_port to honor net namespace
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=66c74d746db127152fadb33f75b2a8ffa4a02b27;p=openwrt%2Fstaging%2Fblogic.git

RDMA/cma: Update cma_validate_port to honor net namespace

cma_validate_port uses rdma_dev_addr to validate the port of the cm_id.
It needs to honor the net namespace which is setup during cm_id creation
when finding netdevice.
