4a1bbe457a ramips: Add byte queue limits support to net/ethernet/ramips_main.c 
Add byte queue limits support to net/ethernet/ramips_main.c

"Byte queue limits are a mechanism to limit the size of the transmit
hardware queue on a NIC by number of bytes. The goal of these byte
limits is too reduce latency (HOL blocking) caused by excessive
queuing in hardware (aka buffer bloat) without sacrificing
throughput."

03810204dc ramips: Rework ramips_eth to not require irqsave locking anymore 
Previously the tx housekeeping was done in a spin_lock_irqsave critical
section which causes irqs to be disabled during that time. Since the
housekeeping is already prepared to be scheduled as a tasklet process
the housekeeping only in softirq context and revise the locking between
the tx path and the housekeeping tasklet by using a normal spin_lock
which in most situations will be a NOP anyway.

This makes sure that interrupts are only disabled for a short time
since in the worst case the housekeeping might have to free up to 256
skbs.

b95eb02775 ramips: initial support for Sitecom WL-351 v1 002 
This add support for the Sitecom WL-351 v1 002.
In principle the Engenius ESR9850 should also work with this, but I
don't have the hardware to test it.

Since an external gigabit switch (RTL8366RB) is used,
I had to modify the ramips_esw driver to add a 'bypass' mode, which
just configures it to not filter the vlan tags.
Also two initialization words (FCT2 and FPA2) are set to different
values by u-boot than what the driver is using and it only seems to
work correctly when they not overridden by the driver, so I
added them to the platform specific data as reg_initval_fct2 and
reg_initval_fpa2.

With this wired lan works as expected, however I'm still having some
trouble with the wireless lan:
It only works after I rmmod & re-insmod rt2800pci and then
reconfigure it in the webinterface, but not directly after
rebooting.

The symptom of this is wpad saying:
Dec 20 15:45:09 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> IEEE 802.11: associated (aid 1)
Dec 20 15:45:09 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> WPA: pairwise key handshake completed (RSN)
Dec 20 15:45:22 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> IEEE 802.11: authenticated

But wpa_supplicant on the client saying:
Authentication with <wl351mac> timed out.
