| Subject: net: usb: r8152: fix transmit queue timeout |
| |
| From: Mingj Ye <insyelu@gmail.com> |
| |
| [ Upstream commit 833dcd75d54f0bf5aa0a0781ff57456b421fbb40 ] |
| |
| When the TX queue length reaches the threshold, the netdev watchdog |
| immediately detects a TX queue timeout. |
| |
| This patch updates the trans_start timestamp of the transmit queue |
| on every asynchronous USB URB submission along the transmit path, |
| ensuring that the network watchdog accurately reflects ongoing |
| transmission activity. |
