This is a series of patches used in OpenWrt's v4.9 backports that seem to be of generic interest to v4.9.y
As a bunch of commits hit networking I CC DaveM and here so the can nod/object to these, I think the want a bit of control over what goes into networking stable.
I avoided two patch sets dealing with IPv6 tunneling and netfilter that seem to still be fixed and I feel generally incompetent about.
For the remaining patches I cherry-picked the upstream commits except for (8/10) "netfilter: nf_tables: fix mismatch in big-endian system" where I used OpenWrt's backport.
The list of upstream commits in patch order: 6db6f0eae6052b70885562e1733896647ec1d807 "bridge: multicast to unicast" e9156cd26a495a18706e796f02a81fee41ec14f4 "smsc95xx: Use skb_cow_head to deal with cloned skbs" 6bc6895bdd6744e0136eaa4a11fbdb20a7db4e40 "ch9200: use skb_cow_head() to deal with cloned skbs" 39fba7835aacda65284a86e611774cbba71dac20 "kaweth: use skb_cow_head() to deal with cloned skbs" 854826c9d526fd81077742c3b000e3f7fcaef3ce "ubifs: Drop softlimit and delta fields from struct ubifs_wbuf" 1b7fc2c0069f3864a3dda15430b7aded31c0bfcc "ubifs: Use dirty_writeback_interval value for wbuf timer" cd4b1e34655d46950c065d9284b596cd8d7b28cd "usb: dwc2: Remove unnecessary kfree" 10596608c4d62cb8c1c2b806debcbd32fe657e7 "netfilter: nf_tables: fix mismatch in big-endian system" 65cab850f0eeaa9180bd2e10a231964f33743edf "net: Allow class-e address assignment via ifconfig ioctl" 6926e041a8920c8ec27e4e155efa760aa01551fd "uapi/if_ether.h: prevent redefinition of struct ethhdr"
