Subject: [PATCH net-next 0/3] introduce skb_for_each_frag()

From: Matteo Croce <[email-masked]>

Introduce skb_for_each_frag, an helper macro to iterate over the SKB frags.

First patch introduces the helper, the second one is generated with
coccinelle and uses the macro where possible.
Last one is a chunk which have to be applied by hand.

The second patch raises some checkpatch.pl warnings because part of
net/tls/tls_sw.c is indented with spaces.

Build tested with an allmodconfig and a test run.

Matteo Croce (3):
  skbuff: add helper to walk over the fraglist
  net: use skb_for_each_frag() helper where possible
  net: use skb_for_each_frag() in illegal_highdma()
