[PATCH net 0/2] Fixes on the Microchip's LAN865x driver

Posted by Parthiban Veerasooran 1 month, 3 weeks ago

This patch series includes two bug fixes for the LAN865x Ethernet MAC-PHY
driver:

1. Fix missing transmit queue restart on device reopen
   This patch addresses an issue where the transmit queue is not restarted
   when the network interface is brought back up after being taken down
   (e.g., via ip or ifconfig). As a result, packet transmission hangs
   after the first down/up cycle. The fix ensures netif_start_queue() is
   explicitly called in lan865x_net_open() to properly restart the queue
   on every reopen.

2. Fix missing configuration for LAN865x Rev.B0/B1 hardware
   This patch applies a required configuration for LAN865x silicon
   revisions B0 and B1, as specified in Microchip Application Note AN1760.
   Without this fix, affected hardware may not initialize or function
   correctly. The patch programs register 0x10077 with the value 0x0028
   during initialization, ensuring compatibility with these hardware
   revisions.

Both patches address issues introduced with the initial driver support and
are marked with the appropriate Fixes: tag.
