From: Jesper Dangaard Brouer Date: Thu, 7 May 2015 14:34:51 +0000 (+0200) Subject: pktgen: adjust flag NO_TIMESTAMP to be more pktgen compliant X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f1f00d8ff60ca056db3805406507483eeb3794d7;p=linux-beck.git pktgen: adjust flag NO_TIMESTAMP to be more pktgen compliant Allow flag NO_TIMESTAMP to turn timestamping on again, like other flags, with a negation of the flag like !NO_TIMESTAMP. Also document the option flag NO_TIMESTAMP. Fixes: afb84b626184 ("pktgen: add flag NO_TIMESTAMP to disable timestamping") Signed-off-by: Jesper Dangaard Brouer Signed-off-by: David S.
