Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:

 1) Prevent index integer overflow in ptr_ring, from Jason Wang.

 2) Program mvpp2 multicast filter properly, from Mikulas Patocka.

 3) The bridge brport attribute file is write only and doesn't have a
    ->show() method, don't blindly invoke it. From Xin Long.

 4) Inverted mask used in genphy_setup_forced(), from Ingo van Lil.

 5) Fix multiple definition issue with if_ether.h UAPI header, from
    Hauke Mehrtens.

 6) Fix GFP_KERNEL usage in atomic in RDS protocol code, from Sowmini
    Varadhan.

 7) Revert XDP redirect support from thunderx driver, it is not
    implemented properly. From Jesper Dangaard Brouer.

 8) Fix missing RTNL protection across some tipc operations, from Ying
    Xue.

 9) Return the correct IV bytes in the TLS getsockopt code, from Boris
    Pismenny.

10) Take tclassid into consideration properly when doing FIB rule
    matching. From Stefano Brivio.

11) cxgb4 device needs more PCI VPD quirks, from Casey Leedom.

12) TUN driver doesn't align frags properly, and we can end up doing
    unaligned atomics on misaligned metadata. From Eric Dumazet.

13) Fix various crashes found using DEBUG_PREEMPT in rmnet driver, from
    Subash Abhinov Kasiviswanathan.
