An upstream change broke brcmfmac when loaded with modparam roamoff=1. As we are carrying a patch that enables roamoff by default on the brcm2708 target to improve stability, wireless is currently broken there. Add a patch to fix brcmfmac with roamoff=1.

Subject: [PATCH wireless-drivers] brcmfmac: fix roamoff=1 modparam
|
|
|
|
When the update_connect_param callback is set, nl80211 expects the flag
|
|
WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is
|
|
only set when modparam roamoff=0, while the callback is set
|
|
unconditionally. Since commit 7f9a3e150ec7 this causes a warning in
|
|
wiphy_register, which breaks brcmfmac.
|
|
|
|
Disable the update_connect_param callback when roamoff=0 to fix this.
|
|
|
|
Fixes: 7f9a3e150ec7 ("nl80211: Update ERP info using NL80211_CMD_UPDATE_CONNECT_PARAMS")
