- Subject: [PATCH] brcmfmac: add support to move wiphy instance into network
- namespace
- To support network namespace the driver must assure all created
- network interfaces are in the same namespace as the wiphy instance
- and flag the support using WIPHY_FLAG_NETNS_OK.
- Verified using two terminals:
- Terminal 1 Terminal 2
- -------------------------- ---------------------------------
- # ip netns add brcm-wifi # iw dev
- phy#0
- Interface wlan3
- ifindex 11
- wdev 0x1
- # ip netns exec brcm-wifi bash
- # iw dev
- # echo $$
- 20337 # iw phy0 set netns 20337
- # iw dev
- phy#0
- Interface wlan3
- ifindex 11
- wdev 0x2
- # iw phy0 interface add wl3.ap type __ap
- # iw dev
- phy#0
- Interface wl3.ap
- ifindex 2
- wdev 0x3
- Interface wlan3
- ifindex 11
- wdev 0x2
- # iw dev
- # iw phy0 set netns 1
- # iw dev
- # iw dev
- phy#0
- Interface wl3.ap
- ifindex 2
- wdev 0x5
- Interface wlan3
- ifindex 11
- wdev 0x4
- Note:
- increasing wdev identifier above indicates issue in
- cfg80211 which is addressed separately.
