[PATCH] sky2: allow dual port usage
If both ports are receiving on the SysKonnect dual port cards, then it appears the bus interface unit can give an interrupt status for frame before DMA has completed. This leads to bogus frames and general confusion. This is why receive checksumming is also messed up on dual port cards. A workaround for the out of order receive problem is to eliminating split transactions on PCI-X. This version is based of the current linux-2.6.git including earlier patch to disable dual ports.
