2009-08-31ucc_geth: Implement suspend/resume and Wake-On-LAN supportAnton Vorontsov
This patch implements suspend/resume and WOL support for UCC Ethernet driver. We support two wake up events: wake on PHY/link changes and wake on magic packet. In some CPUs (like MPC8569) QE shuts down during sleep, so magic packet detection is unusable, and also on resume we should fully reinitialize UCC structures.

2009-08-31ucc_geth: Fix NULL pointer dereference in uec_get_ethtool_stats()Anton Vorontsov
In commit 3e73fc9a12679a546284d597c1f19165792d0b83 ("ucc_geth: Fix IO memory (un)mapping code") I fixed ug_regs IO memory leak by properly freeing the allocated memory. But ethtool_stats() callback doesn't check for ug_regs being NULL, and that causes following oops if 'ethtool -S' is executed on a closed eth device: Unable to handle kernel paging request for data at address 0x00000180 Faulting instruction address: 0xc0208228 Oops: Kernel access of bad area, sig: 11 [#1] ...

2008-11-14net/ucc_geth: Fix oops in uec_get_ethtool_stats()Anton Vorontsov
p_{tx,rx}_fw_statistics_pram are special: they're available only when a device is open. If the device is closed, we should just fill the data with zeroes.

2007-10-10[ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik
For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.
