[PATCH v3 8/9] net/sxe2: support queue setup and control
liujie5 at linkdatatechnology.com
liujie5 at linkdatatechnology.com
Thu Apr 30 12:18:16 CEST 2026
From: Jie Liu <liujie5 at linkdatatechnology.com>
Add support for Rx and Tx queue setup, release, and management.
Implement eth_dev_ops callbacks for rx_queue_setup, tx_queue_setup,
rx_queue_release, and tx_queue_release.
This includes:
- Allocating memory for hardware ring descriptors.
- Initializing software ring structures and hardware head/tail pointers.
- Implementing proper resource cleanup logic to prevent memory leaks
during queue reconfiguration or device close.
