This patch series contains logic for enabling the lossless mode on the
RX rings of the ENETC, and the PAUSE thresholds on the internal FIFO
memory.
During testing it was found that, with the default FIFO configuration,
a sender which isn't persuaded by our PAUSE frames and keeps sending
will cause some MAC RX frame errors. To mitigate this, we need to
ensure
that the FIFO never runs completely full, so we need to fix up a
setting
that was supposed to be configured well out of reset. Unfortunately
this
requires the addition of a new mini-driver.
What happens if the mini driver is not enabled? Then the fixes aren't
applied and bad things happen (now with the addition of flow control),
right?
I'm asking because, if you have the arm64 defconfig its not enabled.
shouldn't it be something like:
