[PATCH] libertas: remove bss_descriptior->networktsf
This value was parsed out, but then nowhere used ... except in some debugfs output. I can't imagine anyone wanting to use this value for anything real (as no other driver exports it), so bye-bye. Along this, made the columns of /sys/kernel/debug/libertas_wireless/*/getscantable align again. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
