Hyper-V: hn: just call vf's ioctl when changing mtu

2025-12-23T05:38:40+00:00

When changing mtu, if a vf is attached to the netvsc interface, just
calling its ioctl to change vf's mtu is good enough.

Hyper-V: hn: rewrite hn rsc swtich to avoid sysctl hang

2025-02-04T13:39:14+00:00

Changing the rsc_switch flag using sysctl to turn rsc on or off
could hang. The orignal code sends request to host to get the
mtu setting. Sometimes the host fails to reply, causing
the thread to sleep forever waiting for the host response.

Use existing cached mtu from hn device instead to avoid calling
host.

No functional change.

Deprecate contigfree(9) in favour of free(9)

2024-07-26T10:45:01+00:00

As of 9e6544dd6e02c46b805d11ab925c4f3b18ad7a4b contigfree(9) is no longer
needed and should not be used anymore.  We leave a wrapper for 3rd party
code in at least 15.x but remove (almost) all other cases from the tree.

This leaves one use of contigfree(9) untouched; that was the original
trigger for 9e6544dd6e02 and is handled in D45813 (to be committed
seperately later).

hyperv/hn: Don't return error when setting media to autoselect

2024-03-14T00:05:19+00:00

Setting media to autoselect would always return EOPNOTSUPP.
As autoselect is the only valid media, this change now returns
success instead.

bpf: Add IfAPI analogue for bpf_peers_present()

2023-10-13T18:33:31+00:00

An interface's bpf could feasibly not exist, in which case
bpf_peers_present() would panic from a NULL pointer dereference.  Solve
this by adding a new IfAPI that could deal with a NULL bpf, if such
could occur in the network stack.
