"Custom PHY" is vague, should we provide more details on added PHY interfaces,
like code names etc....

This gives build error [1] because assigned enum type is wrong, is this
copy/paste error?

  ../drivers/net/ngbe/base/ngbe_hw.c: In function ‘ngbe_set_mac_type’:
  ../drivers/net/ngbe/base/ngbe_hw.c:1835:35: error: implicit conversion from ‘enum ngbe_media_type’ to ‘enum ngbe_link_type’ [-Werror=enum-conversion]
   1835 |                 hw->mac.link_type = ngbe_media_type_unknown;

'DEBUGOUT' already adds '\n' as far as I can see, it log add double line.

There are multiple usages in this patch.
