Difficulty is hardly ever a reason for not implementing a feature. The firmware for these broadcom chips is running a 802.11 stack and as such it determines most part of the beacon, proberesp, etc. That being said there is a firmware api to add vendor IEs. You can check the function brcmf_vif_set_mgmt_ie() which you find in cfg80211.c of the brcmfmac driver. Loading the driver with debug=6 should make the following debug print show up: brcmf_dbg(TRACE, "ADDED ID : %d, Len: %d, OUI:%02x:%02x:%02x\n", vndrie_info->vndrie.id, vndrie_info->vndrie.len, vndrie_info->vndrie.oui[0], vndrie_info->vndrie.oui[1], vndrie_info->vndrie.oui[2]); There are also a couple of error prints, but those would show up anyway. Hope this helps.
