- correct the ethernet payload remainder which must be post-offseted by -14 bytes instead of 0 bytes. This is not very clearly defined in the NCM specification. - add development feature about limiting the maximum datagram count in each NCM payload. - zero-pad alignment data - add TX-interval tuning sysctl Approved by: thompsa (mentor)
