SRU Justification
[Impact]
Microsoft has requested the addition of the "mana" driver from Linux v5.11
[Fix]
This patch set consists of 5 patches that are now in mainline.
The patches add the VF driver for Microsoft Azure Network Adapter (MANA), and also changes the hv_netvsc driver's netvsc/VF binding logic to check both the MAC address and the serial number (this is required by the MANA VF driver).
Microsoft would like to request the following 5 patches in all supported releases:

root@decui-u2004-vf:~# modinfo mana | grep filename
filename: /lib/modules/5.8.0-1032-azure/kernel/drivers/net/ethernet/microsoft/mana/mana.ko
Everything worked as expected in our testing:
1. The MANA driver loads and unloads multiple times without any issue.
2. iperf TX/RX tests run without any issue, and the performance numbers are on par with what we get with the latest mainline kernel: the TX number is pretty good; the RX number is sometimes not great but this is a known issue with the latest mainline kernel as well.
3. "ethtool -S" and "ethtool -L" work as expected.
4. When iperf TX/RX tests are running, changing the number of the MANA NIC TX/RX queues and unloading/reloading the MANA driver work without any issue.
[Where problems could occur]
The driver may have bug(s) that cause a kernel crash. |
