[PATCH 2/3] compat: fix iteration over destination multicast addresses

[Pavel Roskin]

Fix dev_mc_sync() and dev_mc_unsync() in compat-2.6.23.c.  When looking
for synchronized addresses, put "break" inside the above "if" to break
the loop only if there is a match.  Otherwise, advance da_to to the next
address.

[PATCH 3/3] compat: don't define genl_register_mc_group() for Linux 2.6.22 and older

[Pavel Roskin]

compat-2.6.23.h has a different definition of genl_register_mc_group().
Likewise, don't define genl_unregister_mc_group() for old kernels.
