2013-08-15ath9k_htc: do not use bulk on EP3 and EP4Oleksij Rempel1-27/+11
If usb auto suspend is enabled or system run in to suspend/resume cycle, ath9k-htc adapter will stop to response. It is reproducible on xhci HCs. Host part of problem: XHCI do timing calculation based on Transfer Type and bInterval, immediately after device was detected. Ath9k-htc try to overwrite this parameters on module probe and some changes in FW, since we do not initiate usb reset from the driver this changes are not took to account. So, before any kind of suspend or reset, host controller will operate with old parameters. Only after suspend/resume and if interface id stay unchanged, new parameters will by applied. Host will send bulk data with no intervals (?), which will cause overflow on FIFO of EP4. Firmware part of problem: By default, ath9k-htc adapters configured with EP3 and EP4 as interrupt endpoints. Current firmware will try to overwrite ConfigDescriptor to make EP3 and EP4 bulk. FIFO for this endpoints stay not reconfigured, so under the hood it is still Int EP. This patch is revert of 4a0e8ecca4ee commit which trying to reduce CPU usage on some systems. Since it will produce more bug as fixes, we will need to find other way to fix it. here is comment from kernel source which has some more explanation: * Some buggy high speed devices have bulk endpoints using * maxpacket sizes other than 512. High speed HCDs may not * be able to handle that particular bug, so let's warn... in our case EP3 and EP4 have maxpacket sizes = 64!!!

eTSEC has Rx and Tx flow control capabilities that may be enabled through MACCFG1[Rx_Flow, Tx_Flow] bits. These bits must not be set however when eTSEC is operated in Half-Duplex mode. Unfortunately, the driver currently sets these bits unconditionally. This patch adds the proper handling of the PAUSE frame capability register bits by implementing the ethtool -A interface. When pause autoneg is enabled, the controller uses the phy's capability to negotiate PAUSE frame settings with the link partner and reconfigures its Rx_Flow and Tx_Flow settings to match the capabilities of the link partner. If pause autoneg is off, the PAUSE frame generation may be forced manually (ethtool -A). Flow control is disabled by default now. This implementation is inspired by the tg3 driver.
