Thanks for the patch, this driver has been moved, please see

commit 955315b0dc8c8641311430f40fbe53990ba40e33

    qlge: Move drivers/net/ethernet/qlogic/qlge/ to
    drivers/staging/qlge/ 
    The hardware has been declared EOL by the vendor more than 5 years
    ago. What's more relevant to the Linux kernel is that the quality
    of this driver is not on par with many other mainline drivers.

Could you rebase, and send the new version to GregKH as he is the
stable maintainer?
