Public bug reported:

Wlan chip is as follows:
02:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)

Problem:
As the wl driver seems to be the default for this card I ended up with this 
driver after a upgrade to quantal.
However, with this driver, compared to the brcmsmac driver, I get really 
horrible pings on the LAN.

----------------------------------

Steps to reproduce:
I attach a console log for demonstration.

Maybe wl should not be recommended for this chip.
