Title:
  r8125-dkms FTBS in Noble with linux-6.11-hwe kernel

Status in r8125 package in Ubuntu:
  In Progress
Status in r8125 source package in Noble:
  In Progress

Bug description:
  [ Impact ]

  r8125-dkms does not compile from source in Noble with kernel 6.11:

  /var/lib/dkms/r8125/9.011.00/build/r8125_n.c:6255:20: error: initialization of ‘int (*)(struct net_device *, struct ethtool_keee *)’ from incompatible pointer type ‘int (*)(struct net_device *, struct ethtool_eee *)’ [-Werror=incompatible-pointer-types]
   6255 |         .set_eee = rtl_ethtool_set_eee,
        |                    ^~~~~~~~~~~~~~~~~~~
  /var/lib/dkms/r8125/9.011.00/build/r8125_n.c:6255:20: note: (near initialization for ‘rtl8125_ethtool_ops.set_eee’)

  [ Test case ]

  Install the latest linux-6.11 kernel on Noble:

  $ sudo add-apt-repository ppa:canonical-kernel-team/ppa
  $ sudo apt update
  $ sudo apt install linux-image-6.11.0-12-generic \
                     linux-modules-6.11.0-12-generic \
                     linux-modules-extra-6.11.0-12-generic \
                     linux-headers-6.11.0-12-generic

  Install r8125-dkms:

  $ sudo apt install r8125-dkms

  Load the module:

  $ sudo modprobe r8125

  The same procedure should be repeated on linux-6.8 to test for
  possible regressions.

  [ Fix ]

  Patch the code to properly support the new linux 6.11 ABI.

  [ Regression potential ]

  A possible regression is possible in systems using r8125-dkms with the
  new 6.11 kernel
