Subject: brcmfmac: store IEs per virtual interface
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8ff5dc92fe8a50c8c86a8c5971edc78a2e422fb5;p=linux-beck.git

brcmfmac: store IEs per virtual interface

For AP feature the IEs are stored in global structure. For future
functionality like P2P-GO it needs to be stored per virtual interface
so better store it in the virtual interface structure.
