net: stmmac: Rework coalesce timer and fix multi-queue races
[ Upstream commit 8fce3331702316d4bcfeb0771c09ac75d2192bbc ]
This follows David Miller advice and tries to fix coalesce timer in
multi-queue scenarios.
We are now using per-queue coalesce values and per-queue TX timer.
Coalesce timer default values was changed to 1ms and the coalesce frames
to 25.
Tested in B2B setup between XGMAC2 and GMAC5.
