* ramips: Add byte queue limits support to net/ethernet/ramips_main.cGabor Juhos2012-05-231-0/+8
| | | | | | | | | | | | | | 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."

* ramips: Rework ramips_eth to not require irqsave locking anymoreJohn Crispin2012-01-171-6/+9
| | | | | | | | | | | | | | | | | 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.

* ramips: initial support for Sitecom WL-351 v1 002Gabor Juhos2011-12-231-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
