From d079abd181950a44cdf31daafd1662388a6c4d2e Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Thu, 21 May 2015 12:16:11 +0200 Subject: pktgen: adjust spacing in proc file interface output Too many spaces were introduced in commit 63adc6fb8ac0 ("pktgen: cleanup checkpatch warnings"), thus misaligning "src_min:" to other columns.

This is not very useful for shell scripting, as it can only detect the error by parsing dmesg. Instead return -EINVAL when the command is unknown, as this provides userspace shell scripting a way of detecting this. Also bump version tag to 2.75, because (1) reading /proc/net/pktgen/pgctrl output this version number which would allow to detect this small semantic change, and (2) because the pktgen version tag have not been updated since 2010.
