* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (82 commits) ipw2200: Call netif_*_queue() interfaces properly. netxen: Needs to include linux/vmalloc.h [netdrvr] atl1d: fix !CONFIG_PM build r6040: rework init_one error handling r6040: bump release number to 0.18 r6040: handle RX fifo full and no descriptor interrupts r6040: change the default waiting time r6040: use definitions for magic values in descriptor status r6040: completely rework the RX path r6040: call napi_disable when puting down the interface and set lp->dev accordingly. mv643xx_eth: fix NETPOLL build r6040: rework the RX buffers allocation routine r6040: fix scheduling while atomic in r6040_tx_timeout r6040: fix null pointer access and tx timeouts r6040: prefix all functions with r6040 rndis_host: support WM6 devices as modems at91_ether: use netstats in net_device structure sfc: Create one RX queue and interrupt per CPU package by default sfc: Use a separate workqueue for resets sfc: I2C adapter initialisation fixes ...
