[RFCv4 1/2] mac80211: fix WPA with VLAN on AP side with ps-sta

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When sending a broadcast while at least on of the connected stations is
sleeping, it gets queued and send after a DTIM beacon is sent.
If the packet was to be sent on a vlan interface, the vif used for dequeing
from the per-bss queue does not hold the per-vlan sdata. The correct sdata is
required to use the correct per-vlan broadcast/multicast key.

This patch fixes this by restoring the per-vlan sdata using the skb->dev entry.
