Subject: [RFC PATCH ipsec 0/2] Fix bonding IPSec races

These patches are an alternate proposed fix to the bonding IPSec races
which could result in unencrypted IPSec packets on the wire.
I'm sending them as RFC based on the discussion with Sabrina on the
primary approach [1].

Cosmin Ratiu (2):
  xfrm: Add explicit offload_handle to some xfrm callbacks
  bonding: Maintain offloaded xfrm on all devices
