Raw ethernet packet

[pctj101]

I noticed that if I carelessly use esp_eth_tx() to send raw packets that it tends to kill my MQTT sessions. Probably something nasty going on.

I see there's some LWIP stuff, and an ethernet_output() call that a lot of other stuff uses.. seems to be a more systematic way to queue/send... but didn't quite see a clear way to use it in my app_main() section of code.

Anything I should beware of as I start digging down to prevent a bigger mess? Is there a right way to use this?

Wanted to bump this back up in case anyone could share anything they know about raw ethernet packet sending causing problems in a multi-task freertos environment.
