so the mmap interface should work between a 64-bit kernel and 32-bit userland *if* the kernel supports TPACKET_V2, as libpcap should choose TPACKET_V2 rather than TPACKET_V1 if TPACKET_V2 is supported.
I tried building 32-bit versions of top-of-trunk libpcap and tcpdump on my 64-bit Ubuntu 10.10 virtual machine, and running the resulting version of tcpdump; it appeared to work OK.- This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
