2010-10-01tg3: Fix potential netpoll crashMatt Carlson
Up until now the tg3 driver would call netif_napi_add() for the maximum number of NAPI instances the driver could use. The problem is that netpoll could call tg3_poll() on instances that are not active. The net effect is that the driver will crash attempting to dereference uninitialized pointers. The fix is to only allocate as many NAPI instances as the driver would use in tg3_open() and deleted them in tg3_close().

2010-09-30e1000e: use hardware writeback batchingJesse Brandeburg
Most e1000e parts support batching writebacks. The problem with this is that when some of the TADV or TIDV timers are not set, Tx can sit forever. This is solved in this patch with write flushes using the Flush Partial Descriptors (FPD) bit in TIDV and RDTR. This improves bus utilization and removes partial writes on e1000e, particularly from 82571 parts in S5500 chipset based machines. Only ES2LAN and 82571/2 parts are included in this optimization, to reduce testing load.

This patch contains the following DCA improvements to myri10ge: 1) Finally move myri10ge to use dca3 API 2) Disable PCIe relaxed ordering when enabling DCA on myri10ge. This provides a performance boost on Nehalem based Xeons 3) Make sure to properly initialize NIC's DCA state when it is enabled, rather than giving the NIC a bogus tag (0) and waiting for the first received packet to trigger an update. Not using a real tag can cause hardware exceptions on some motherboards when a CPU socket is empty. 3) Always update the cached CPU when our interrupt affinity changes so as to avoid excessive calls to dca3_get_tag() Signed-off-by: Andrew Gallatin <gallatin@myri.com> Signed-off-by: Loic Prylli <loic@myri.com> Signed-off-by: David S.
