Subject: gen_uuid.c (uuid_generate_time): Fix bug pointed out by Ralf
X-Git-Tag: E2FSPROGS-1_35-WIP-0131~6
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=9c5534d48470471ec3480458b661e80d8bcfad66;p=tools%2Fe2fsprogs.git

gen_uuid.c (uuid_generate_time): Fix bug pointed out by Ralf
	S. Engelshall; when generating a random ethernet address
	because one is not available, set the least significant
	bit of the first byte of the MAC address, since it is the
	first bit to be transmitted, and is therefore the
	multicast bit.
