Merge branch 'net-core-improvements-to-device-lookup-by-hardware-address'
Breno Leitao says:
====================
net: core: improvements to device lookup by hardware address.
The first patch adds a new dev_getbyhwaddr() helper function for
finding devices by hardware address when the rtnl lock is held. This
prevents PROVE_LOCKING warnings that occurred when rtnl lock was held
but the RCU read lock wasn't. The common address comparison logic is
extracted into dev_comp_addr() to avoid code duplication.
The second coverts arp_req_set_public() to the new helper.
