Subject: RDMA/cma: Refactor to access multiple fields of rdma_dev_addr
X-Git-Tag: v4.16-rc1~137^2~32
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2493a57bc10f4f67d241711b058e42c0b0f1b31a;p=thirdparty%2Fkernel%2Flinux.git

RDMA/cma: Refactor to access multiple fields of rdma_dev_addr

Pass the rdma_cm_id so that multiple fields of the rdma_dev_addr
structure can be accessed, instead of passing each individual fields.

This is needed to access some additional fields in followup patches.
