This driver is not working because of problems of its receiving code.
This patch fixes it to make it work.
When the driver receives an LAPB frame, it should first pass the frame
to the LAPB module to process. After processing, the LAPB module passes

Add setter for BTF FD to allow application more fine-grained control in more

This patch set improves libbpf's support of old kernels, missing features like

kernels that have no BTF su

With valid ELF and valid BTF, there is no reason (apart from bugs) why BTF

Cater to devices which:
(a) may want to sleep in the callbacks;
(b) only have IPv4 support;
(c) need all the programming to happen while the netdev is up.
Drivers attach UDP tunnel offload info struct to their netdevs,
where they declare how many UDP ports of various tunnel types
they support.

Make use of new common udp_tunnel_nic infra. ixgbe supports
IPv4 only, and only single VxLAN and Geneve ports (one each).
I'm dropping the confusing piece of code in ixgbe_set_features().
ndo_udp_tunnel_add and ndo_udp_tunnel_del did not check if RXCSUM
is enabled, so this code was either unnecess

Add an interface to report offloaded UDP ports via ethtool netlink.
Now that core takes care of tracking which UDP tunnel ports the NICs
are aware of we can quite easily export this information out to
user space.
The responsibility of writing the netlink dumps is split between
ethtool code and ud
Kernel has a facility to notify drivers about the UDP tunnel ports
so that devices can recognize tunneled packets. This is important
mostly for RX - devices which don't support CHECKSUM_COMPLETE can
report checksums of inner packets, and compute RSS over inner headers.
Some drivers also match the U

Now that there are USXGMII constants available, drop the old definitions
and reuse the generic ones.

This is a resend [now a new v4] of the series because the conversion to the
phylink interface will likely take longer:
https://lore.kernel.org/netdev/CA+h21hpBodyY8CtNH2ktRdc2FqPi=Fjp94=vvzvzsvbnvnf...@mail.gmail.com/
Also the discussion in the v3 resend doesn't look like it will be resolved
soon :
ENETC has ethernet MACs capable of SGMII, 2500BaseX and USXGMII. But in
order to use these protocols some SerDes configurations need to be
performed. The SerDes is configurable via an internal PCS PHY which is
connected to an internal MDIO bus at address 0.
This patch basically removes the depende

Use DT information rather than in-band information from bootloader to
set up MAC for XGMII. For RGMII use the DT indication in addition to
RGMII defaults in hardware.
However, this implies that PHY connection information needs to be
extracted before netdevice creation, when t
The constants are taken from the USXGMII Singleport Copper Interface

This is essentially the two first patches of the previous

The queue reset pattern is used in a couple different places,
only slightly different from each other, and could cause
issues if one gets changed and the other didn't. This puts
them together so that only one version is needed, yet each
can have slighty different effects by passing in a pointer
