X-Git-Tag: v2.6.19-rc3~13^2~8

[PATCH] e1000: Reset all functions after a PCI error

During the handling of the PCI error recovery sequence, the current e1000
driver erroneously blocks a device reset for any but the first PCI
function.  It shouldn't -- this is a cut-n-paste error from a different
driver (which tolerated only one hardware reset per hardware card).
