 3) Fix race in updating pause settings in bnxt_en, from Vasundhara
    Volam.

 4) Propagate error return properly during unbind failures in ax88172a,
    from George Kennedy.

 5) Fix memleak in adf7242_probe, from Liu Jian.

 6) smc_drv_probe() can leak, from Wang Hai.

 7) Don't muck with the carrier state if register_netdevice() fails in
    the bonding driver, from Taehee Yoo.

 8) Fix memleak in dpaa_eth_probe, from Liu Jian.

 9) Need to check skb_put_padto() return value in hsr_fill_tag(), from
    Murali Karicheri.

10) Don't lose ionic RSS hash settings across FW update, from Shannon
    Nelson.

11) Fix clobbered SKB control block in act_ct, from Wen Xu.

12) Missing newlink in "tx_timeout" sysfs output, from Xiongfeng Wang.

13) IS_UDPLITE cleanup a long time ago, incorrectly handled
    transformations involving UDPLITE_RECV_CC. From Miaohe Lin.

14) Unbalanced locking in netdevsim, from Taehee Yoo.

15) Suppress false-positive error messages in qed driver, from Alexander
    Lobakin.

16) Out of bounds read in ax25_connect and ax25_sendmsg, from Peilin Ye.

17) Missing SKB release in cxgb4's uld_send(), from Navid Emamdoost.

18) Uninitialized value in geneve_changelink(), from Cong Wang.

19) Fix deadlock in xen-netfront, from Andera Righi.

19) flush_backlog() frees skbs with IRQs disabled, so should use
    dev_kfree_skb_irq() instead of kfree_skb(). From Subash Abhinov
    Kasiviswanathan.

2) Device creation with multiple proto mode enabled
2) Device creation with multiproto mode enabled
There are two ways to create a bareudp device for MPLS & IP with multiproto mode
enabled.
The multiproto mode allows bareudp tunnels to handle several protocols of the
same family. It is currently only available for IP and MPLS. This mode has to
be enabled explicitly with the "multiproto" flag.
a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype 0x8847 multiproto
a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype ipv4 multiproto
b) ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls
For an IPv4 tunnel the multiproto mode allows the tunnel to also handle
IPv6.
b) ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls_uc multiproto
For MPLS, the multiproto mode allows the tunnel to handle both unicast
and multicast MPLS packets.
