* net/fec: restore interrupt mask after software-reset in fec_stop()Wolfram Sang2010-07-221-3/+4
| | | | | | | | | | | After the change from mdio polling to irq, it became necessary to restore the interrupt mask after resetting the chip in fec_stop(). Otherwise, with all irqs disabled, no communication with the PHY will be possible after e.g. un-/replugging the cable and the device gets stalled.

* net: preserve ifreq parameter when calling generic phy_mii_ioctl().Richard Cochran2010-07-191-1/+1
| | | | | | | | | | | | The phy_mii_ioctl() function unnecessarily throws away the original ifreq. We need access to the ifreq in order to support PHYs that can perform hardware time stamping. Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl(). This is unnecessary since phylib will check the command in any case.

* fec: use interrupt for MDIO completion indicationBaruch Siach2010-07-131-30/+25
| | | | | | | | | | | | With the move to phylib (commit e6b043d) I was seeing sporadic "MDIO write timeout" messages. Measure of the actual time spent showed latency times of more than 1600us. This patch uses the MII event indication of the FEC hardware to detect completion of MDIO transactions. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: David S.

* net/fec: clean suspend/resumeEric Benard2010-06-261-18/+12
| | | | | | | | | | | | | | | | Commit 59d4289b83b11379d867e2f7146904b19cc96404 converted fec to dev_pm_ops but didn't update the suspend/resume functions thus leading to the following warning : "initialization from incompatible pointer type" when CONFIG_PM is set. This patch also fixe a few indentation and style around CONFIG_PM area.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f0b3fbeae11a526c3d308b691684589ee37c359b ("FEC Buffer rework") breaks transmission of packets where the skb data buffer is not memory aligned according to FEC_ALIGNMENT. It incorrectly passes to dma_sync_single() the buffer address directly from the skb, instead of the address calculated for use (which may be the skb address or one of the bounce buffers). It seems there is no use converting the cpu address of the buffer to a physical either, since dma_map_single() expects the cpu address and will return the dma address to use in the descriptor. So remove the use of __pa() on the buffer address as well. This patch is against 2.6.30-rc5. This breakage is a regression over 2.6.30, which does not have this problem.

* | fec: replace flush_dcache_range with dma_sync_singleSascha Hauer2009-02-011-2/+5
| | | | | | | | | | | | | | | | | | | | flush_dcache_range is not portable across architectures. Use dma_sync_single instead. Also, the memory must be synchronised in the receive path aswell.
