Subject: arping: fix sent vs received packages return value
|
||
|
|
|
||
|
|
My earlier signalfd() and timerfd() work really messed up sent vs received
|
||
|
|
package counter comparison, and related command return value. Basically
|
||
|
|
everything always mismatched, and that was expected with corner case of one
|
||
|
|
package only that did match and caused none-zero return. Oh my, that is
|
||
|
|
pretty much as wrong the code could have been.
