net: cadence_gem: Add Tx descriptor fetch printf
Add a debug printf for TX descriptor fetching. This is helpful to anyone needing to debug TX ring buffer traversal. It is also now consistent with the RX code which has a similar printf. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
