    SubjectRe: Fixing rt2500pci [PATCH]

    In kernel version 2.6.26-rc9 my wireless LAN card worked; but in the
    released 2.6.26, my RaLink rt2500 card wouldn't associate.

    Git-bisect led me to this patch:

    rt2x00: Remove ieee80211_tx_control argument from write_tx_desc()

    I believe that there is a problem with that patch --- it
    (inadvertantly) removes an extra line of code, that used to set the

    This patch reinstates that line, and with it my card works again.

    The original version I sent still used the skbdesc->data_len which has
    been removed; this version of the patch applies on top of 2.6.27-rc1.
