This patch series represents the first phase. We plan to integrate it in
two phases: the first phase covers mailbox and chip configuration,
while the second phase involves net dev configuration.
Together, they will provide basic PF-based Ethernet port transmission and
reception capabilities.

After that, we will consider other features, such as ethtool support,
flow management, adminq messaging, VF support, debugfs support, etc.

The coccicheck bot flagged a new Coccinelle warning introduced by the
nebula-matrix driver series:

  drivers/net/ethernet/nebula-matrix/nbl/nbl_main.c:187:45-52:
    WARNING: Consider using %pe to print PTR_ERR()

The scripts/coccinelle/misc/ptr_err.cocci rule fires when a PTR_ERR()
value is passed to a format string without using the %pe specifier,
which is the kernel-preferred way to print error pointers (it displays
both the numeric value and the symbolic name).

Please fix nbl_main.c line 187 to use %pe instead of passing the raw
PTR_ERR() value to %ld or similar.

For example, change something like:
  pr_err("...: %ld\n", PTR_ERR(ptr));
to:
  pr_err("...: %pe\n", ptr);
