I'd say this semantically changes the code.

argh,
sorry,

Subject: [PATCH] wireless/zd1211rw: use  get_unaligned_le16 helper (v2)

Signed-off-by: Sebastian Andrzej Siewior <redacted>

After applying this patch, things seem better. I can associate to an 
open access point, get an IP address and even ping.

However on association, I am still seeing:

and when I start pinging the AP, this starts chiming in:

I also cannot get a full scan with:

iwlist wlan0 scanning

I get about 4 APs (I know there's more) then a bus error. This may be 
related to a similar problem that I was assisted with in my first round 
of posts last year, with regards to the wireless-tools. Perhaps the 
patches still haven't made it downstream?

Thanking you for help,
Shaddy
