e1f6d0dd0a ralink: fix tx vlan offload and hardware status
hardware status and tx vlan offload support on all targets
except rt5350. so i modify the IS_ENABLE condition only for
mt7621.
support mt7621 hardware status reference by SDK. but i don't
have mt7621. if not work just set mt7621 FE_REG_FE_COUNTER_BASE
to 0 to let software count.

ced0cf3a94 move ethernet hw init to init/uninit functions
This should fix the stalled irq problem seen by several people.
This is not the real fix, but rather moves the bug to the un/init patch of the driver.
The real bug still needs to be fixed, but this workaround should be suffcient to make
the ethernet stable.

d8b2fef763 ramips: Add missing andmask to ramips_esw register read for recv_good value.
Add missing andmask to ramips_esw register read for recv_good value.

Without the mask, recv_bad leaks into the recv_good packet count.
Didn't notice the bug before since you don't usually get bad
packets, so I only saw it when I was playing with overlength packets
earlier...

04c6143ca9 ramips: Use doubletagging to disable ramips_esw vlan by default, it seems more reliable.
Use doubletagging to disable ramips_esw vlan by default, it seems
more reliable.

Daniel Golle found an issue where sometimes (possibly only for
RT3352) the default vlan disable method (clearing en_vlan, untag,
doubletag and putting all ports into vlan 0) doesn't work and the
packets get sent out vlan-tagged with vlan 0.

Instead switch to using the doubletagging method (allow doubletagged
packets, put all ports into vlan 0 with untag enabled) by default.

Unless someone figures out a way to really globally disable vlan for
this switch, this seems like the best (most reliable) option.

I did some tests regarding maximum packet size and did not see any

difference between the two methods, both allow for slightly bigger packets
than the ramips_main.c ethernet driver (ping stops going through
above "ping -s 1472" (1514 bytes), on the switch packets are recv_good until
"ping -s 1490", or about 1532 bytes).

Haven't measured this myself yet, but according to this

it can save about 300mW of power.

bb0785880a ramips: Rename POC registers
Rename POC registers.

The current code uses POC1-POC3.

The datasheet uses:
POC1: Port Control 0
POC1: Port Control 1
POC2: Port Control 2

So the first POC1 is a typo that should have been POC0, rename the
registers to POC0-POC2 accordingly.

f1b9d77912 ramips: Minor ramips_esw.c cleanup
Stop handling VLAN setup in the kernel.
Removes the obsolete RT305X_ESW_VLAN_CONFIG_BYPASS option I added for
WL-351 and add some extra comments.
Also removes the en_vlan per-port flag that isn't very useful really, it now
is only controlled by the global enable_vlan flag.

3b17f1deb8 ramips: Add swconfig support to ramips_esw.c
Add swconfig support to ramips_esw.c

This patch adds swconfig support for ramips_esw:

Tested on both D-LINK DIR-300 B1 and Sitecom WL-351 (external
rtl8366rb on internal port 5).
I've made sure that in the enable_vlan=0 case it behaves like a dumb
switch, so external switches should work fine with vlans and
verified this on the WL-351.

The current state shown by swconfig is always read directly from HW
registers, new settings only show after 'swconfig dev rt305x set apply'.

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."
