(shurd) - iflib - Fix queue capping checks (mmacy) - iflib - Fix invalid assert, em can need 2 sentinels (mmacy) - iflib - let the driver determine what capabilities are set and what tx csum flags are used (mmacy) - add INVARIANTS debugging hooks to gtaskqueue enqueue (mmacy) - update bnxt(4) to support the changes to iflib (shurd) Some other various, sundry updates.
