rt2400pci, rt2500pci and rt61 require different txdone handling, but the code that pushes the frame upstream and cleans up the entry is identical to all of them. This will create the function rt2x00pci_txdone() to remove the duplicate code. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
