tap_lsc_intr_handle_set(): intr callback unregister failed: -2<br>
free(): invalid pointer<br>

<br>
Quick debug shows that in 'pmd->intr_handle->fd' is '0' may be reason of the<br>
error.<br>
Ferruh, I think this because of the intr_vec, so there should be a way to differentiate if vec was used or not ? Or should we just assume that if the fd is 0 then intr_vec was installed. ? </blockquote></div></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
