The minimum and maximum limits for resources assigned to a given
resource group are programmed in pairs, with the limits for two
groups set in a single register.
If the number of supported resource groups is odd, only half of the
register that defines these limits is valid for the last group; that
Adding Ido here, he has some more experience with the do's and dont's
here, and therefore might have one or two ideas to share.

TIPC reserves 64 service types for current and future internal use.
Therefore, the bind() function is meant to block regular user sockets
from being bound to these values, while it should let through such
bindings from internal users.
However, since we at the design moment saw no
Sometimes it takes longer than 5 seconds to complete failover,
migration, and other resets. In stead of scheduling another timeout reset,
we wait for the current one to complete.

This patch adds a check to see if we support libbpf. By default the
system libbpf will be used, but static linking against a custom libbpf
version can be achieved by passing LIBBPF_DIR to configure. FORCE_LIBBPF
can be set to force configure to abort if no suitable libbpf is found,
which is useful

Add support for non-blocking recvmsg() to XDP sockets. Previously,
only sendmsg() was supported by XDP socket. Now, for symmetry and the
upcoming busy-polling support, recvmsg() is added.

This series converts iproute2 to use libbpf for loading and attaching
BPF programs when it is available. This means that iproute2 will
correctly process BTF information and support the new-style BTF-defined
maps, while keeping compatibility with the old internal map definition
syntax.

Dimitry, you added this code, can you please look into
that?

Extend the bridge multicast control and data path to configure routes
for L2 (non-IP) multicast groups.
The uapi struct br_mdb_entry union u is extended with another variant,
mac_addr, which does not change the structure size, and which is valid
when the proto field is
Users should try use the new BTF defined maps instead of struct
bpf_elf_map defined maps. The tail call examples are not added yet
as libbpf doesn't currently support declaratively populating tail call
maps.
