Subject: [PATCH v4 net-next 00/11] nbl driver for Nebulamatrix NICs
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.
ps:The "nbl_core" issue has not been modified yet as it is still under discussion.
(https://lore.kernel.org/netdev/17d3aa72-23a8-4ea8-9721-bc20fe39fdf4.sam.chen@nebula-matrix.com/)
We will make the modification once a conclusion is reached.
Excluding patch 3,4, the total comes to about 5000 lines.
