Subject: [PATCH v3 net-next 00/15] nbl driver for Nebulamatrix NICs
The patch series add the nbl driver, which will support nebula-matrix
18100 and 18110 series of network cards.
This submission is the first phase. which only supports the PF-based
Ethernet transmit and receive functionality. Once this is merged.
will submit addition patches to implement support for other
features. such as ethtool support, flow management, adminq msg, vf
support, debugfs support and etc.
chanages v2 →v3
Link to v2: https://lore.kernel.org/netdev/20260109100146.63569-1-illusion.wang@nebula-matrix.com/
1.cut down to a mini driver:
delete vf support
use promisc mode to cut down flow management
drop patch15 in v2
delete adminq msg
delete abnormal handling
delete some unimportant interfaces
2.modify issues found by ai review
Changes v1->v2
