Re: possible memory leak or memory waste

[Ben Greear <greearb@candelatech.com>]

Default firmware has a hard-coded minimum number of tx buffers (somewhere
more than 1k buffers I think).  Maybe driver is allocating all this
memory somehow?

If you do one-way traffic tests (udp), I wonder if you can tell if it is tx
or rx that consumes the memory?

CT firmware can be configured to use any multiple-of-8 amount of tx
buffers, though I have not tested below around 600.

Thanks,
Ben
