Hi,
On 6.8.0-rc3-next-20240208, the network interfaces are not getting configured.
Thanks for the report. Could you please elaborate on what "not getting
configured" means in detail?
- Any error in any log?
- Any other error message?
- Interface doesn't come up or which specific configuration are you missing?
I am not seeing any errors in the dmesg,

If the interfaces aren't up, please try to bring them up manually and see what happens.
ip link set <if> up
Nothing happens.

I have 'NetXtreme BCM5720 Gigabit Ethernet PCIe'
configuration: autonegotiation=on broadcast=yes driver=tg3
If I revert below commit I am able to get back the interfaces mentioned.

tg3: convert EEE handling to use linkmode bitmaps
Convert EEE handling to use linkmode bitmaps. This prepares for
removing the legacy bitmaps from struct ethtool_keee.
No functional change intended.
Note: The change to mii_eee_cap1_mod_linkmode_t(tp->eee.advertised, val)
in tg3_phy_autoneg_cfg() isn't completely obvious, but it doesn't change
the current functionality.
