Subject: [net-next 0/3] ip_gre: a bunch of fixes for mtu
Date: Mon, 9 Oct 2017 13:47:44 -0700 [thread overview]
Message-ID: <1507582067-36718-1-git-send-email-u9012063@gmail.com> (raw)
The first two patches are to fix some issues for mtu and needed_headroom length
calculation from the gre and erspan tunnel header. The last path tries to avoid
arithmetic operation for every packet when checking for erspan truncate.
William Tu (3):
ip_gre: fix mtu and headroom size
ip_gre: fix erspan tunnel mtu calculation
ip_gre: cache the device mtu hard_header_len calc
