When closing the driver or reinitializing the hardware there is the usual del_timer() race condition that exists when timers re-add themselves. Fix by conversion to del_timer_sync(). Signed-off-by: NRalf Baechle <ralf@linux-mips.org> Signed-off-by: NJeff Garzik <jeff@garzik.org>

changes due to qe_lib changes include: o removed inclusion of platform header file o removed platform_device code, replaced with of_device o removed typedefs o uint -> u32 conversions o removed following defines: QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER, BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET because they hid sizeof/in_be32/out_be32 operations from the reader. o removed irrelevant comments, added others to resemble removed BD_ defines o const'd and uncasted all get_property() assignments bugfixes, courtesy of Scott Wood, include: - Read phy_address as a u32, not u8. - Match on type == "network" as well as compatible == "ucc_geth", as device_is_compatible() will only compare up to the length of the test string, allowing "ucc_geth_phy" to match as well. - fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

The reason sky2 driver was locking up on transmit on the Yukon-FE chipset is that it was misconfiguring the internal RAM buffer so the transmitter and receiver were sharing the same space. The code assumed there was 16K of RAM on Yukon-FE (taken from vendor driver sk98lin which is even more f*cked up on this). Then it assigned based on that. The giveaway was that the registers would only hold 9bits so both RX/TX had 0..1ff for space. It is a wonder it worked at all! This patch addresses this, and fixes an easily reproducible hang on Transmit. Only the Yukon-FE chip is Marvell 88E803X (10/100 only) are affected.

During the handling of the PCI error recovery sequence, the current e1000 driver erroneously blocks a device reset for any but the first PCI function. It shouldn't -- this is a cut-n-paste error from a different driver (which tolerated only one hardware reset per hardware card).

This reverts commit 4596c75c as requested by Olaf Hering. It causes compile errors, and says Olaf: "This change is also wrong, the autoloading works perfect with 2.6.18, no need to add random PCI ids. See commit a0245f7a, platform devices have now a modalias entry in sysfs. The network card is not a PCI device." Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Fixes the implementation of the ethtool set ring parameters for the tg3 transmit ring. The size of tx_pending is taken into account before doing a netif_wake_queue.

The pci express error handling extensions don't work unless PCI access is via mmconfig. Otherwise, all accesses to pci config registers greater than 256 fail. Since the sky2 driver has other ways of getting to PCI config space, it works around this short coming, but the pci_find_ext_capablity doesn't work. This backs out commit 91aeb3ed Go back to hardcoding, since we know where the error registers are anyway.
