Subject: [PATCH net-next 0/7] net: Remove unused function parameters in
 skbuff.c

Couple of cleanup patches to get rid of unused function parameters around
skbuff.c.

Offshot of my question in [1], but way more contained. Found by adding
"-Wunused-parameter -Wno-error" to KBUILD_CFLAGS and grepping for specific
skbuff.c warnings.
