  Log Message:
  -----------
  conntrack: Exclude l2 padding in 'conn_key_extract()'.

'conn_key_extract()' in userspace conntrack is including L2
(Ethernet) pad bytes for both L3 and L4 sizes. One problem is
any packet with non-zero L2 padding can incorrectly fail L4
checksum validation.

This patch fixes conn_key_extract() by ignoring L2 pad bytes.

Fixes: a489b16854b5 ("conntrack: New userspace connection tracker.")
