- * Revision History:
- * 1.13 64-bit proof.
- * 1.14 Do not round-up transmit length.
- * 1.15 Define TC35815_DMA_SYNC_ONDEMAND, cleanup.
- * 1.16 Fix free_page bug introduced in 1.15
- * 1.17 Add mii/ethtool ioctl support.
- * Remove workaround for early TX4938. Cleanup.
- * 1.20 Kernel 2.6.
- * 1.21 Fix receive packet length (omit CRC).
- * Call netif_carrier_on/netif_carrier_off.
- * Add kernel/module options (speed, duplex, doforce).
- * Do not try "force link mode" by default.
- * Reconfigure CAM on restarting.
- * Reset PHY on restarting.
- * Add workaround for 100MHalf HUB.
- * 1.22 Minor fix.
- * 1.23 Minor cleanup.
- * 1.24 Remove tc35815_setup since new stype option
- * ("tc35815.speed=10", etc.) can be used for 2.6 kernel.
- * 1.25 TX4939 support.
- * 1.26 Minor cleanup.
- * 1.27 Move TX4939 PCFG.SPEEDn control code out from this driver.
- * Cleanup init_dev_addr. (NETDEV_REGISTER event notifier
- * can overwrite dev_addr)
- * support ETHTOOL_GPERMADDR.
- * 1.28 Minor cleanup.
- * 1.29 support netpoll.
- * 1.30 Minor cleanup.
- * 1.31 NAPI support. (disabled by default)
- * Use DMA_RxAlign_2 if possible.
- * Do not use PackedBuffer.
- * Cleanup.
- * 1.32 Fix free buffer management on non-PackedBuffer mode.
- * 1.33 Fix netpoll build.
- * 1.34 Fix netpoll locking. "BH rule" for NAPI is not enough with
- * netpoll, hard_start_xmit might be called from irq context.
- * PM support.
