* ramips: ramips_eth: use Kconfig definition to enable debugjuhosg2012-11-251-1/+1
| | | | | | | | | | The Kconfig identifier to enable debugging in the driver was different from the actually used one. Fix that.

* [ramips] move ethernet hw init to init/uninit functionsblogic2012-11-121-17/+29
| | | | | | | | | 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. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@34177 3c298f89-4303-0410-b956-a3cf2f4a3e73

* ramips: Add missing andmask to ramips_esw register read for recv_good value.juhosg2012-09-051-1/+3
| | | | | | | | | | | | | 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...

* ramips: Use doubletagging to disable ramips_esw vlan by default, it seems ↵juhosg2012-09-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 http://www.8devices.com/community/viewtopic.php?f=6&t=156 it can save about 300mW of power.

* ramips: Rename POC registersjuhosg2012-08-291-31/+31
| | | | | | | | | | | | | | | | | | 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.

* ramips: Minor ramips_esw.c cleanupjuhosg2012-08-291-59/+3
| | | | | | | | | | | | 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.

* ramips: Add swconfig support to ramips_esw.cjuhosg2012-08-292-35/+755
| | | | | | | | | | | | | | | | | | | 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'.

* ramips: watchdog: use maximum possible timeout by defaultjuhosg2012-08-121-6/+6
| | | | | | | | | | | | | As the userspace has no means to determine the maximum possible timeout, use that as the default and let the userspace lower it when necessary. As the result the usual OpenWrt install (with busybox's watchdog trying to set the timeout to 60s on start) is using a 33s timeout on an RT3052 clocked at 384MHz instead of the current 20s default.

| | | | | | | | | | | | | | | | | 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.
