Hello:

This patch was applied to netdev/net.git (main)
by Jakub Kicinski [off-list ref]:

sparx5_fdma_xmit() advances dcb_index before checking that the FDMA is
done with the DCB, and does not undo the advance when the check fails.
Before commit f4aa7e361ae2 ("net: sparx5: use FDMA library for adding
DCB's in the tx path") the next DCB was always the one after last_dcb.
Since then dcb_index drifts one DCB further away from last_dcb on every
failed transmit.
