As I just stated, many of the patches in the "current" patch series have 
already been applied to netdev-2.6.git#upstream:

Linas Vepstas (11):
       s2io: add PCI error recovery support
       s2io: add PCI error recovery support
       spidernet: beautify error messages
       spidernet: move a block of code around
       spidernet: zero out a pointer.
       spidernet: null out skb pointer after its been used.
       spidernet: Don't terminate the RX ring
       spidernet: enhance the dump routine
       spidernet: reset the card when an rxramfull is seen
       spidernet: service TX later.
       spidernet: increase the NAPI weight

These are clearly duplicating some of the patches in your patchseries, 
which means you are woefully out of sync with upstream.
