Runnining LEDE snapshot, let me know if you want any more info

[yuhhaurlin]

This is warning message, I think the system can still work. I will check and remove this warning.

[yuhhaurlin]

Can you let me know which version of driver you used? I check current code, this kind of warning message should not happen.

[yuhhaurlin]

I close this issue. If you still encounter this problem on current driver, please let me know.

@yuhhaurlin
This still seems to happen (running a LEDE snapshot from https://davidc502sis.dynamic-dns.net/ on a WRT3200ACM)

Linux version 4.14.44 (davidc502@pc2) (gcc version 7.3.0 (OpenWrt GCC 7.3.0 r7093-4fdc6ca31b)) #0 SMP Fri Jun 1 19:01:03 2018
<<Marvell Mac80211 Wireless PCIE Network Driver version 10.3.4.0-20180330>>

Don't know how often that happens, have seen it for the first time today. System still seems to work though.
