Subject: [PATCH 0/2] do not disable sg when packet requires no checksum

This two-part patchset replaces an earlier net-only patch that
added an explicit check for the AoE protocol to harmonize_features
in net/core/dev.c.

Following the suggestions of Ben Hutchings, this patchset makes
the decision in the network layer protocol agnostic instead of
using ETH_P_AOE as a special case.  It relies on fresh skbs being
CHECKSUM_NONE but makes that explicit with an assertion.

Ed L. Cashin (2):
  aoe: assert AoE packets marked as requiring no checksum
  net: do not disable sg for packets requiring no checksum
