====================
net: aquantia: various ethtool ops implementation
In this patchset Anton Mikaev and I added some useful ethtool operations:
- ring size changes
- link renegotioation
- flow control management
The patch also improves init/deinit sequence.
V3 changes:
- After review and analysis it is clear that rtnl lock (which is
captured by default on ethtool ops) is enough to secure possible
overlapping of dev open/close. Thus, just dropping internal mutex.
V2 changes:
- using mutex to secure simultaneous dev close/open
- using state var to store/restore dev state
