Add driver for Microchip LAN87XX T1 PHYs
This patch support driver for Microchp T1 PHYs.
There will be followup patches to this driver to support T1 PHY
features such as cable diagnostics, signal quality indicator(SQI),
sleep and wakeup (TC10) support.

Hey everyone,
This is the new approach to uevent filtering as discussed (see the

Instead of duplicating the decision regarding port forwarding state made
by mlxsw_sp_port_vid_stp_set(), extract the decision-making into a new

UDP GSO needs to export __udp_gso_segment to call it from ipv6.
I accidentally exported static ipv4 function __udp4_gso_segment.

Avoid exiting the function with a lingering sysfs file (if the first
call to device_create_file() fails while the second succeeds), and avoid
calling devlink_port_unregister() twice.
In other words, either mlx4_init_port_info() succeeds and returns zero, or
it fails, returns non-zero, and requires

The struct vhost_msg within struct vhost_msg_node is copied to userspace,

When adding tcp mmap() implementation, I forgot that socket lock
had to be taken before current->mm->mmap_sem. syzbot eventually caught
the bug.
Since we can not lock the socket in tcp mmap() handler we have to
split the operation in two phases.
1) mmap() on a tcp socket simply reserves VMA space
