Joe Perches 8329419a29 Staging: Convert uses of compare_ether_addr to ether_addr_equal
Preliminary to removing compare_ether_addr altogether:

Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

Additionally:

Used is_zero_ether_addr, removed now unused variable
Converted uses of &foo[0] to foo

Done via cocci script: (and a little typing)

$ cat compare_ether_addr.cocci

Peter Huewe 97b3e0ed1d staging/slicoss: Use ether_crc for mac hash calculation
Instead of performing the hash calculation for the mac address by ourself, we
can simply reuse ether_crc and shift only the result according to our
needs.
The code was tested against the previous implementation by verifying both
implementations against each other in userspace for 16200000000 different
mac addresses, changing the vendor bits of the mac address first.
