Igor Russkikh 94b3b54230 net: aquantia: vlan unicast address list correct handling
Setting up macvlan/macvtap networks over atlantic NIC results
in no traffic over these networks because ndo_set_rx_mode did
not listed UC MACs as registered in unicast filter.

Here we fix that taking into account maximum number of UC
filters supported by hardware. If more than MAX addresses were
registered, we just enable promisc  and/or allmulti to pass
the traffic in.

We also remove MULTICAST_ADDRESS_MAX constant from aq_cfg since
thats not a configurable parameter at all.

Fixes: b21f502 ("net:ethernet:aquantia: Fix for multicast filter handling.")

Igor Russkikh b647d39809 net: aquantia: Add tx clean budget and valid budget handling logic
We should report to napi full budget only when we have more job to do.
Before this fix, on any tx queue cleanup we forced napi to do poll again.
Thats a waste of cpu resources and caused storming with napi polls when
there was at least one tx on each interrupt.

With this fix we report full budget only when there is more job on TX
to do. Or, as before, when rx budget was fully consumed.

Igor Russkikh efe779b749 net: aquantia: Introduce new device ids and constants
New set of aquantia devices has an upgraded hardware (B1).
The hardware interface is identical to B0. The difference will
be in firmware which is incompatible with old one.

Reorganized and removed duplicate speed and devid definitions
Introduced explicit flow control configuration defines

Igor Russkikh fdb4a0830e net: aquantia: Improve link state and statistics check interval callback
Reduce timeout from 2 secs to 1 sec. If link is down,
reduce it to 500msec. This speeds up link detection.

Igor Russkikh b82ee71a86 net: aquantia: Enable coalescing management via ethtool interface
Aquantia NIC allows both TX and RX interrupt throttle rate (ITR)
management, but this was used in a very limited way via predefined
values. This patch allows to setup ITR default values via module
command line arguments and via standard ethtool coalescing settings.

Igor Russkikh 3aec6412e0 aquantia: Fix Tx queue hangups
Driver did a poor job in managing its Tx queues: Sometimes it could stop
tx queues due to link down condition in aq_nic_xmit - but never waked up
them. That led to Tx path total suspend.
This patch fixes this and improves generic queue management:
- introduces queue restart counter
- uses generic netif_ interface to disable and enable tx path
- refactors link up/down condition and introduces dmesg log event when
  link changes.
- introduces new constant for minimum descriptors count required for queue
  wakeup

Pavel Belous 5900eca1ac aquantia: Fix driver name reported by ethtool
V2: using "aquantia" subsystem tag.

The command "ethtool -i ethX" should display driver name (driver: atlantic)
instead vendor name (driver: aquantia).
