[Intel-wired-lan] Intel E810-XXVDA2 no link at 25G - 10G works and so does forcing 25G via ethtool

Hello intel-wired-lan, I might post to the wrong place /ML as this issue could not be caused by an issue with the driver / kernel module. But I already tried my luck with Intel support (ticket# 06047421). Support was active at first, but now the conversation there seems to have died off unfort

[Intel-wired-lan] Kernel E810-XXV or E810-CQDA2 cause "NETDEV WATCHDOG: iface (ice): transmit queue xy timed out" if LACP bonding is used

Hello intel-wired-lan, we experienced some kernel warnings / crashes on multiple machines when using LACP bonding on our E810-CQDA2 nics running on Ubuntu 22.04 LTS (Jammy) and on HWE kernel 6.2.0-36-generic. The two 100G ports of the nics were bonded using LACP and (likely unrelated, via ML
