X-Git-Tag: v6.15-rc1~160^2~261^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=80604d19b5fc3bc309039670445c73ee418d7a01;p=thirdparty%2Fkernel%2Flinux.git

net: pktgen: enable 'param=value' parsing

Enable more flexible parameters syntax, allowing 'param=value' in
addition to the already supported 'param value' pattern (additional
this gives the skipping '=' in count_trail_chars() a purpose).

Tested with:

	$ echo "min_pkt_size 999" > /proc/net/pktgen/lo\@0
	$ echo "min_pkt_size=999" > /proc/net/pktgen/lo\@0
	$ echo "min_pkt_size =999" > /proc/net/pktgen/lo\@0
	$ echo "min_pkt_size= 999" > /proc/net/pktgen/lo\@0
	$ echo "min_pkt_size = 999" > /proc/net/pktgen/lo\@0
