From 3fb4ef7d39abbb2f8f6cd349e4af11082bf8c8c4 Mon Sep 17 00:00:00 2001 From: Maksim Kiselev Date: Wed, 19 Jul 2023 09:53:37 +0300 Subject: [PATCH] net: axi_emac: Change return value to -EAGAIN if RX is not ready If there is no incoming package than axiemac_recv will return -1 which in turn leads to printing `eth_rx: recv() returned error -1` error message in eth_rx function. But missing a package is not an fatal error, so return -EAGAIN in that case would be more suitable.
