From dd70ff481526a87f69bec732fcc402c60441560c Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 6 Jan 2021 15:16:01 +0100 Subject: [PATCH] net: ks8851: Reset internal RXFC count on bad packet A sporadic condition occurs when the "bad packet" error is triggered repeatedly, which results in "bad packet" messages scrolling on the console during transfer. To avoid triggering this, reset the internal RXFC count on the first occurance of the "bad packet", which forces the code to re-read the RX packet count from the MAC, and prevents any additional "bad packet" messages if there are no more packets in the MAC. Also print better debug information if this condition occurs.
