f8d2b1f3f7 Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (2 of many) 
r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked). Use it in
preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

74954211d6 net: add ETHER_IS_ZERO macro similar to ETHER_IS_BROADCAST 
Some places in network code may need to verify that an ethernet address
is not the 'zero' address. Provide a standard macro ETHER_IS_ZERO for
this purpose, similar to the ETHER_IS_BROADCAST macro already available.

This patch also removes previous ETHER_IS_ZERO definitions in several
USB ethernet drivers, in favor of this centrally-located macro.

cef38d45bb In some cases like NanoPI R1, its second USB ethernet 
RTL8152 (chip version URE_CHIP_VER_4C10) doesn't
have hardwired MAC address, in other words, it is all zeros.
This commit fixes it by setting random MAC address
when MAC address is all zeros.

d7c5a620e2 ifnet: Replace if_addr_lock rwlock with epoch + mutex 
Run on LLNW canaries and tested by pho@

gallatin:
Using a 14-core, 28-HTT single socket E5-2697 v3 with a 40GbE MLX5
based ConnectX 4-LX NIC, I see an almost 12% improvement in received
packet rate, and a larger improvement in bytes delivered all the way
to userspace.

When the host receiving 64 streams of netperf -H $DUT -t UDP_STREAM -- -m 1,
I see, using nstat -I mce0 1 before the patch:

e1b74f21f5 Add initial support for RTL8152 USB Fast Ethernet. RTL8152 supports 
IPv4/IPv6 checksum offloading and VLAN tag insertion/stripping.

Since uether doesn't provide a way to announce driver specific offload
capabilities to upper stack, checksum offloading support needs more work
and will be done in the future.

Special thanks to Hayes Wang from RealTek who gave input.
