Hi Broadcom folks,
We are now enabling a new platform with tg3 nic, unfortunately we observed
the bug [1] that dated back to 2015.
I tried commit 4419bb1cedcd ("tg3: Add workaround to restrict 5762 MRRS to
2048”) but it does’t work.
Do you have any idea how to solve the issue?

With link aware mode, the clock speed could be slow and boot code does not
complete within the expected time with lower link speeds. Need to override
and the clock in driver. We are checking the feasibility of adding
this in driver or firmware.

I built a kernel and asked affected users to try.
Thanks for your work.
