Fix OdroidC2 Gigabit Tx link issue
This patchset fixes an issue with the OdroidC2 board (DWMAC + RTL8211F).
The platform seems to enter LPI on the Rx path too often while performing
relatively high TX transfer. This eventually break the link (both Tx and
Rx), and require to bring the interface down and up again to get the Rx
path working again.
The root cause of this issue is not fully understood yet but disabling EEE
advertisement on the PHY prevent this feature to be negotiated.
With this change, the link is stable and reliable, with the expected
throughput performance.
The patchset adds options in the generic phy driver to disable EEE
advertisement, through device tree. The way it is done is very similar
to the handling of the max-speed property.
Changes since V2: [2]
- Rename "eee-advert-disable" to "eee-broken-modes" to make the intended
purpose of this option clear (flag broken configuration, not a
configuration option)
- Add DT bindings constants so the DT configuration is more user friendly
- Submit to net-next instead of net.
Changes since V1: [1]
- Disable the advertisement of EEE in the generic code instead of the
realtek driver.

This patch adds an option to disable EEE advertisement in the generic PHY
by providing a mask of prohibited modes corresponding to the value found in
the MDIO_AN_EEE_ADV register.
On some platforms, PHY Low power idle seems to be causing issues, even
breaking the link some cases. The patch provides a convenient way for these
platforms to disable EEE advertisement and work around the issue.

The dwmac4 IP can synthesized with 1-8 number of tx queues.
On an IP synthesized with DWC_EQOS_NUM_TXQ > 1, all txqueues are disabled
by default. For these IPs, the bitfield TXQEN is R/W.
Always enable tx queue 0. The write will have no effect on IPs synthesized
with DWC_EQOS_NUM_TXQ == 1.
The driver does still not utilize more than one tx queue in the IP.

Marvell Wifi PCIe modules don't always behave nicely for PCIe power
management when their firmware hasn't been loaded, particularly after
suspending the PCIe link one or more times. When this happens, we might
end up spinning forever in this status-polling tight loop. Let's make
this less tight by adding a timeout and by sleeping a bit in between
reads, as we do with the other similar loops.
This prevents us from hogging a CPU even in such pathological cases, and
allows the FW initialization to just fail gracefully instead.
I chose the same polling parameters as the earlier loop in this
function, and empirically, I found that this loop never makes it more
than about 12 cycles in a sane FW init sequence. I had no official
information on the actual intended latency for this portion of the
download.

Issue description:
Current implementation saves the ETS settings from user in
a temporal soft copy and returns this settings when user
queries the ETS settings.
With the new DCBX firmware, the ETS settings can be changed
by firmware when the DCBX is in firmware controlled mode. Therefore,
user will obtain wrong values from the temporal soft copy.
Solution:
1. Read the ETS settings directly from firmware.
2. For tc_tsa:
a. Initialize tc_tsa to vendor IEEE_8021QAZ_TSA_VENDOR at netdev
creation.
b. When reading ETS setting from FW, if the traffic class bandwidth
is less than 100, set tc_tsa to IEEE_8021QAZ_TSA_ETS. This
implementation solves the scenarios when the DCBX is in FW control
and willing bit is on which means the ETS setting is dictated
by remote switch.
Also check ETS capability where needed.
