Log: MFC 308908,308909 308908 hyperv/hn: Allow enabling IPv6 TX checksum offloading and IPv6 TSO. They are still disabled by default. Sponsored by: Microsoft Differential Revision: https://reviews.freebsd.org/D8490 308909 hyperv/hn: Don't abuse hn_{tx,rx}_ring_inuse. Just in case, the # of TX/RX rings is changed upon synthetic parts re-attach.
