Hi, thanks for the patch. >> but, btpand should also ensure that the buffer sizes are suitable. The >> server_init() function already does this in FreeBSD, though I also added >> some code to increase the RCVBUF size in NetBSD code, and also added (but >> didn't yet commit) the similar for client code.. I will prepare a patch > > patch for btpand attached I tried your patch and it works, I do not need the kernel patch for the default size of NG_BTSOCKET_L2CAP_SENDSPACE anymore. Now I describe another problem with my ping test, I am not sure if this problem concerns btpand too. If the ICMP packet must be fragmented, then the first fragment ist lost on the tap interface (and can not be found by tcpdump running on this tap) if an ARP request is necessary. ping -c 1 -s 1400 panserver works all the time, ping -c 1 -s 1600 panserver only works if the ip address of panserver is in the arp cache. I did nothing special with the tap interface, it is included in my "cloned_interfaces" in rc.conf and opened by btpand. Any ideas ? Andreas Longwitz
