[PATCH] ubusd: convert tx_queue to linked list

[Sergey Zakharchenko]

Hi Arnout,

JFYI: Much of your patch resembles
https://patchwork.ozlabs.org/project/lede/patch/20180503100622.11168-1-i@qbox.audio/
which was marked superseded for no apparent reason, but "anonymous
remembers":).

As for the limits, one of them could include a timeout (e.g. no
progress in writing to client for over 10s => ubusd closes
connection).

Best regards,
