[lwip-devel] [bug #51033] LWIP_ASSERT while doing repetitive transmission

[Fayek]

Follow-up Comment #8, bug #51033 (project lwip):

Simon,

I'm working with Preet on this issue. We were able to identify the root cause
of the LWIP_ASSERT. The problem occurs when we have fully consumed all
available descriptors inside our Ethernet tx function and return ERR_BUF to
the calling function inside LWIP. Our solution was to place a system wait
inside the transmit function until the tx output was no longer full rather
than exiting the tx function and returning an error.

Not sure why LWIP is handling ERR_BUF returns with an assert.
