2008-09-24ixgbe: add clean rx many routineJesse Brandeburg
in some configurations there can be more than one rx queue per vector in msi-x mode. Add functionality to be able to clean this without changing the performance path single-rx-queue cleanup.

changing ring sizes in ethtool needs to be robust. If an allocation fails the driver must continue operation, with the previous settings.

2008-09-24ixgbe: recycle pages in packet split modeJesse Brandeburg
most of the time we only need 1500 bytes for a packet which means we don't need a whole 4k page for each packet. Share the allocation by using a reference count to the page and giving half to two receive descriptors. This can enable us to use packet split mode all the time due to the performance increase of allocating half the pages.

2008-09-248139too: [cosmetic] fix incorrect register for flash-romMats Erik Andersson
I would like to submit a correction to the driver drivers/net/8139too.c, which in no way changes the compiled driver, but does change the value of a previously incorrect value for the configuration register address of Flash PROM on the network processor rtl8139C. This corrected value is in accordance with the datasheet for rtl8139C, and in addition this new value is indeed used in other functional drivers that use this adapter for programming a Flash memory chip in situ. But as said, the two new constants are never referenced in the driver maintained by you: they are only informational and correct!

2008-09-24[netdrvr] atl1e: Don't take the mdio_lock in atl1e_probeMatthew Wilcox
Lockdep warns about the mdio_lock taken with interrupts enabled then later taken from interrupt context. Initially, I considered changing these to spin_lock_irq/spin_unlock_irq, but then I looked at atl1e_phy_init() and saw that it calls msleep(). Sleeping while holding a spinlock is not allowed either. In the probe path, we haven't registered the interrupt handler, so it can't poke at this card yet. It's before we call register_netdev(), so I don't think any other threads can reach this card either. If I'm right, we don't need a spinlock at all.

2008-09-24[netdrvr] au1000_eth: Spinlock initialisation fixMartin Gebert
Seems like the spinlock for the AU1x00 ethernet device is initialised too late, as it is already used in enable_mac(), which is called via mii_probe() before the init takes place. The attached patch is working here for a Linux Au1100 2.6.22.6 kernel, and as far as I checked should also be applicable to the current head (just line numbers differ).
