Problem with 2.6.22 / Unknown symbol netif_subqueue_stopped

Problem with 2.6.22 / Unknown symbol netif_subqueue_stopped

[Mark S.]

Hello!

I'm running kernel 2.6.22. I've compiled and installed the wireless dri=
vers=20
from your latest tarball, which the documentation says should work with=
=20
2.6.22.  I'm using the kernel source for KLIB_BUILD. When attempting to=
 load=20
the resulting module zd1211rw, there is a cascade of errors starting wi=
th=20

  mac80211:  Unknown symbol netif_subqueue_stopped

Scanning through your wireless drivers and through the kernel source, I=
 don't=20
see where this exact symbol is defined. I see that it is called for=20
in /net/mac80211/tx.c And  I  see that __netif_subqueue_stopped is defi=
ned in=20
compat.h. But not netif_subqueue_stopped. Googling online, it appears t=
hat=20
netif_subqueue_stopped may be first defined in 2.6.23 in the kernel, th=
ough=20
I'm not sure on that point. =20

=46inally, I deleted tx.o and compiled again to be able to catch the me=
ssages. I=20
have  pasted the messages at the bottom of this message. The upshot is =
that a=20
great many symbols, but netif_subqueue_stopped in particular, do not ap=
pear=20
to be defined anywhere.

Please let me know If I'm looking in the wrong place for this symbol, a=
nd=20
what, if anything, I can do about it.

Thanks!
Mark

This required MQ backport which I just finished an attempt for, please
give it a try and let me know how it goes.
