B2 WLAN ECO questions

[Tiago Marques]

Hi all,

In an effort to migrate testing to a machine that resembles something
like the C1, I would like to perform the WLAN ECO(s) on the B2 1.5.
However, I found one for the B2 models and another for the B3:

http://wiki.laptop.org/go/XO1.5_WLAN_SR_ECO
http://wiki.laptop.org/go/XO1.5_WLAN_power_ECO

Do I only need to do the XO1.5_WLAN_power_ECO, or does the SR ECO also
apply to the B2? From the wiki page it seems a B3 problem only but
AFAIK the B3 is B2+ ECOs, so it would need it too. What am I missing?

Best regards,
Tiago
