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.
