Subject: udp_send: Fix com_off.
X-Git-Tag: v0.4.2~13^2
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=91edaa02c232edf82b93a928058c044df80badc1

udp_send: Fix com_off.

When the off command is executed, the udp sender sends an eof packet
to all configured targets. However, it then continues to send data.

Fix this by returning early in udp_send_fec() if the sender has been
switched off.
