Subject: [PATCH 0/3] Add get/set ethernet address functions and ACPI MAC address pass through functionality to cdc_ncm driver
Date: Fri, 30 Aug 2019 19:36:22 +0000 [thread overview]
Message-ID: <1567193782174.28980@Dellteam.com> (raw)
In recent testing of a Dell Universal Dock D6000, I found that MAC
address pass through is not supported in the Linux drivers. However,
this same device is supported in Windows 10 (Pro) on my personal
computer, in as much as I was able to tell Windows to assign a new MAC
address of my choosing, and I saw through wireshark the new MAC address
was pushed out to the device. Afterward, Windows reported a new IP
address and I was able to view web pages.
This series of patches give support to cdc_ncm USB based Ethernet
controllers for programming a MAC address to the device, and also to
retrieve the device's MAC address. This patch series further adds ACPI
MAC address pass through support specifically for the cdc_ncm driver, and
generally for any other driver that may need or want it, in furtherance of
Dell's enterprise IT policy efforts. It was this latter that I initially
found lacking when testing a D6000 with a Dell laptop, and then I found
ifconfig was unable to set a MAC address into the device. These patches
bring a similar level of functionality to cdc_ncm driver as is available
with the Realtek r8152 driver, and is available with Windows.
The cdc_ncm driver limits the ACPI MAC address pass through support to
only the Dell Universal Dock D6000, so no other cdc_ncm device will be
impacted.
