Subject: sfc: Merge falcon_probe_phy() into falcon_probe_port()
X-Git-Tag: firefly_0821_release~9833^2~3968^2~718
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=96c45726c7dd5ee11b8773810208c41e40a93ffd;p=firefly-linux-kernel-4.4.55.git

sfc: Merge falcon_probe_phy() into falcon_probe_port()

MAC and PHY probing are bound up together, as evidenced by the
initialisation of efx_nic::loopback_modes.  Remove the current
arbitrary separation.
