Commit 377cf82d authored by Denis V. Lunev's avatar Denis V. Lunev Committed by David S. Miller

[RAW]: Family check in the /proc/net/raw[6] is extra.

Different hashtables are used for IPv6 and IPv4 raw sockets, so no
need to check the socket family in the iterator over hashtables. Clean
this out.
