We use 8192cu and 8811AU provided by Realtek. Our kernel is 3.10.
We would like to add parallel support for ath10k_pci from backports.
However after inserting compat.ko, cfg80211.ko and mac80211.ko from
backports, 8192cu.ko and 8821au.ko terminate with following message:
[ 512.188364] 8192cu: Unknown symbol wiphy_new (err 0)
[ 512.188481] 8192cu: Unknown symbol cfg80211_send_disassoc (err 0)
[ 512.188554] 8192cu: Unknown symbol cfg80211_send_rx_assoc (err 0)
[ 512.188607] 8192cu: Unknown symbol cfg80211_inform_bss_frame (err 0)
Those interfaces are exported when I load cfg80211.ko compiled from kernel 3.10.
But I can not see them in cfg80211.ko provided by backports.
Do you know this problem ?
Is there any easy way to solve this issue ?

Seems they were renamed/cleaned in patch:
cfg80211/mac80211: clean up cfg80211 SME APIs
so, newest cfg80211.ko don't have them.
Patch for 8192cu seems to be required - at least to use this new API.
