2010-01-08netxen: fix set mac addrAmit Kumar Salecha
o If tx and rx resources are not available, during set mac request. Then this request wont be passed to firmware and it will be added to driver mac list and will never make it to firmware.

2010-01-07TI DaVinci EMAC: Handle emac module clock correctly.Sriram
In the driver probe function the emac module clock needs to be enabled before calling register_netdev(). As soon as the device is registered the driver get_stats function can be invoked by the core - the module clock must be switched on to be able to read from stats registers. Also explicitly call matching clk_disable for failure conditions in probe function. Signed-off-by: Sriramakrishnan <srk@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-01-07dmfe/tulip: Let dmfe handle DM910x except for SPARC on-board chipsBen Hutchings
The Davicom DM9100 and DM9102 chips are used on the motherboards of some SPARC systems (supported by the tulip driver) and also in PCI expansion cards (supported by the dmfe driver). There is no difference in the PCI device ids for the two different configurations, so these drivers both claim the device ids. However, it is possible to distinguish the two configurations by the presence of Open Firmware properties for them, so we do that.

2010-01-07mv643xx_eth: don't include cache padding in rx desc buffer sizeSaeed Bishara
If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth allocates a couple of extra bytes at the start of each receive buffer to make the data payload end up on a cache line boundary. These extra bytes are skb_reserve()'d before DMA mapping, so they should not be included in the DMA map byte count (as the mapping is done starting at skb->data), nor should they be included in the receive descriptor buffer size field, or the hardware can end up DMAing beyond the end of the buffer, which can happen if someone sends us a larger-than-MTU sized packet. This problem was introduced in commit 7fd96ce47ff ("mv643xx_eth: rework receive skb cache alignment", May 6 2009), but hasn't appeared to be problematic so far, probably as the main users of mv643xx_eth all have NET_SKB_PAD == L1_CACHE_BYTES.

2010-01-03via-velocity: Give RX descriptors to the NIC later on open or MTU changeBen Hutchings
velocity_open() calls velocity_give_many_rx_descs(), which gives RX descriptors to the NIC, before installing an interrupt handler or calling velocity_init_registers(). I think this is very unsafe and it appears to explain the bug report <http://bugs.debian.org/508527>. On MTU change, velocity_give_many_rx_descs() is again called before velocity_init_registers(). I'm not sure whether this is unsafe but it does look wrong. Therefore, move the calls to velocity_give_many_rx_descs() after request_irq() and velocity_init_registers().

On suspend: - PM core starts suspending devices, ucc_geth_suspend gets called; - ucc_geth calls phy_stop() on suspend. Note that phy_stop() is mostly asynchronous so it doesn't block ucc_geth's suspend routine, it just sets PHY_HALTED state and disables PHY's interrupts; - Suddenly the state machine gets scheduled, it grabs the phydev->lock mutex and tries to process the PHY_HALTED state, so it calls phydev->adjust_link(phydev->attached_dev). In ucc_geth case adjust_link() calls msleep(), which reschedules the code flow back to PM core, which now finishes suspend and so we end up sleeping with phydev->lock mutex held. On resume: - PM core starts resuming devices (notice that nobody rescheduled the state machine yet, so the mutex is still held), the core calls ucc_geth's resume routine; - ucc_geth_resume restarts the PHY with phy_stop()/phy_start() sequence, and the phy_*() calls are trying to grab the phydev->lock mutex. Here comes the deadlock. This patch fixes the issue by stopping the state machine on suspend and starting it again on resume.
