Linux 7.3 adds the 8250_mxpcie driver for Moxa PCIe multi-port serial boards and removes the older IPWireless driver.
The new driver gives kernel-level support for Moxa’s PCIe serial adapters, which are common in industrial and embedded deployments. Removing the IPWireless driver means any system still relying on that driver will lose built-in support and must migrate to an alternative. Upgrading to Linux 7.3 therefore resolves a missing-driver issue for new hardware while introducing a compatibility gap for legacy setups.

The 8250_mxpcie driver is merged into the Linux 7.3 TTY/Serial subsystem for Moxa PCIe multi-port serial boards.
The legacy IPWireless serial driver is dropped from the kernel in the same release.
Systems that need the new Moxa support must run Linux 7.3 or later, and any existing IPWireless users must replace or backport the driver.
