crda refused to build on Ubuntu 13.10 (crda failed linking to 
libgcrypt... but I have no clue why, as lreg linked fine and lgcrypt 

I have a new install with:
-Ubuntu 12.04 LTS (no support for ath10k yet)
-got firmware via
-builded linux-3.13.5 to have the ath10k modules (nog atk10k from source 
see my mail of 24 Feb)
-builded hostapd, wireless-regdb and crda from source

and I have 80MHz wide channels now :-)

Just got a stable 160Mbps (iperf udp, tweeking the distance and ended up 
around 50cm) on a Ubuntu 13.10 client (regulatory.bin still not ok).
Not yet the 300Mbps as I read earlier on the thread.
What could be the next steps to speed up the link?

Thanks a lot,
