From: Lorenzo Bianconi Date: Wed, 27 May 2026 10:21:19 +0000 (+0200) Subject: net: airoha: Move {cpu,fwd}_tx_packets in airoha_gdm_dev struct X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=962c17dd287887aa87a6f30d64239d7e1e4e05fa;p=thirdparty%2Flinux.git net: airoha: Move {cpu,fwd}_tx_packets in airoha_gdm_dev struct Since now multiple net_devices connected to different QDMA blocks can share the same GDM port, cpu_tx_packets and fwd_tx_packets fields can be overwritten with the value from a different QDMA block. In order to fix the issue move cpu_tx_packets and fwd_tx_packets fields from airoha_gdm_port struct to airoha_gdm_dev one.
