-Subject: net: stmmac: dwmac-socfpga: Set RX watchdog interrupt as broken
-
-From: Maxime Chevallier <maxime.chevallier@bootlin.com>
-
-[ Upstream commit 407618d66dba55e7db1278872e8be106808bbe91 ]
-
-On DWMAC3 and later, there's a RX Watchdog interrupt that's used for
-interrupt coalescing. It's known to be buggy on some platforms, and
-dwmac-socfpga appears to be one of them. Changing the interrupt
-coalescing from ethtool doesn't appear to have any effect here.
-
-Without disabling RIWT (Received Interrupt Watchdog Timer, I
-believe...), we observe latencies while receiving traffic that amount to
-around ~0.4ms. This was discovered with NTP but can be easily reproduced
-with a simple ping. Without this patch :
-
-64 bytes from 192.168.5.2: icmp_seq=1 ttl=64 time=0.657 ms
-
-With this patch :
