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

Pull networking fixes and cleanups from David Miller:

 1) Use rb_entry() instead of hardcoded container_of(), from Geliang
    Tang.

 2) Use correct memory barriers in stammac driver, from Pavel Machek.

 3) Fix assoc bind address handling in SCTP, from Xin Long.

 4) Make the length check for UFO handling consistent between
    __ip_append_data() and ip_finish_output(), from Zheng Li.

 5) HSI driver compatible strings were busted fro hix5hd2, from Dongpo
    Li.

 6) Handle devm_ioremap() errors properly in cavium driver, from Arvind
    Yadav.
