linux-toradex.git/drivers/usb/class, branch v6.4-rc2 Linux kernel for Apalis and Colibri modules wwan: core: Support slicing in port TX flow of WWAN subsystem 2023-03-18T05:38:31+00:00 haozhe chang haozhe.chang@mediatek.com 2023-03-16T09:58:20+00:00 36bd28c1cb0dbf48645cfe43159907fb3253b33a wwan_port_fops_write inputs the SKB parameter to the TX callback of the WWAN device driver. However, the WWAN device (e.g., t7xx) may have an MTU less than the size of SKB, causing the TX buffer to be sliced and copied once more in the WWAN device driver. This patch implements the slicing in the WWAN subsystem and gives the WWAN devices driver the option to slice(by frag_len) or not. By doing so, the additional memory copy is reduced. Meanwhile, this patch gives WWAN devices driver the option to reserve headroom in fragments for the device-specific metadata.
