** Description changed:
+ [SRU Justification]
+
+ [Impact]
+
+ Missing firmware for Realtek RTL8125B 2.5Gb Ethernet-NIC, which
+ is supported by linux-oem-5.10 kernel.
+
+ [Fix]
+
+ Two upstream commit necessary:
+ * commit 3890db36665d ("rtl_nic: add firmware for RTL8125B")
+ * commit 69c7f0bdc76e ("rtl_nic: update firmware for RTL8125B")
+
+ [Test Case]
+
+ Without firmware, drive probe would fail with:
+
+ $ dmesg | grep -i r8169
+ r8169 0000:06:00.0: unknown chip XID 641
+
+ With firmware, it should then succeed:
+
+ $ dmesg | grep -i r8169
+ r8169 0000:07:00.0 eth0: RTL8125B, b4:2e:99:ef:c6:82, XID 641, IRQ 66
+ r8169 0000:07:00.0 eth0: jumbo features [frames: 9194 bytes, tx
checksumming: ko]
+ r8169 0000:07:00.0 eno1: renamed from eth0
+ RTL8125B 2.5Gbps internal r8169-700:00: attached PHY driver [RTL8125B
2.5Gbps internal] (mii_bus:phy_addr=r8169-700:00, irq=IGNORE)
+
+ [Where problems could occur]
+
+ While this introduces new firmware blobs and enabled devices supported
+ by new kernels, it should have little effect on existing systems, but
+ with new devices up and running, it may still affect power consumptions,
+ ability to enter deep suspend, etc.
+
+ [Other Info]
+
+ RTL8125B is supported by Linux kernel since v5.9 and on, so only Focal
+ is nominated specifically for linux-oem-5.10 kernel.
