Another test this morning with heavy downloading (but tcp only)
show slot usage auf max 204/256. we are using firmware
"version 666.2 (2011-02-23 01:15:07)" which is OpenWrt's default
for b43. see here the full logs, including minstrel output and dmesg:
http://intercity-vpn.de/files/openwrt/b43test2.dmesg.txt
if a slot needs ~2500 bytes, so 256 slot are only 640kb which seems
ok to me. ofcourse it raises the memory consumption by 500kb, but now
the router is useful 8-)
thank you! bye, bastian
