Subject: [PATCH net-next 0/2] Allow disabling pause frames on panic

This patch set allows disabling pause frame generation upon encountering
a kernel panic. This has proven to be helpful in lab environments where
devices are still being worked on, will panic for various reasons, and
will occasionally take down the entire Ethernet switch they are attached
to.
