Josh Wu	3e4dad5032	tools: gen_eth_addr: add getpid() to time(0) to avoid duplicated seed ... As 'time(0) | getpid()' will have a lot of duplicated value. It is not a expected behavior. We expect different value for the seed when when run it in many times. So this patch will left shift the getpid() and add to time(0). That avoid duplicated value. Test command is like: % RUN=0; while [ $RUN -lt 10000 ]; do tools/gen_eth_addr; RUN=$(($RUN+1)); done | sort | uniq | wc -l 10000 This patch is incorporated with suggestions made by Wolfgang Denk and Andreas Bießmann. Thanks them a lot.

Peter Tyser	2eeb4e95fb	gen_eth_addr: Use POSIX rand() and srand() ... Replace random()/srandom() use with rand()/srand() to support compilation with the mingw toolchain. The rand()/srand() functions are generally more common and are functionally equivalent to the original random()/srandom() calls.
