All of the error paths in pci_vtcon_sock_add free the sock pointer.
However, sock is not initialized until part way through the function.
An early error would pass stack garbage to free().

When initializing the device model for a PCI pass through device that
uses MSI-X, bhyve reads the MSI-X capability from the real device to
save a copy in the emulated PCI config space. It also saves a copy in
a local struct msixcap on the stack. Since struct msixcap is packed,
GCC complains that casting a pointer to the struct to a uint32_t
pointer may result in an unaligned pointer.
This path is not performance critical, so to appease the compiler,
simply change the pointer to a char * and use memcpy to copy the 4
bytes read in each iteration of the loop.

The ident string for NVMe and VirtIO block deivces do not contain the

Adding a bare constant to a uint16_t promotes to a signed int which

scrub rules have defaulted to handling fragments for a long time, but
since we removed "fragment crop" and "fragment drop-ovl" in 64b3b4d611
this has become less obvious and more expensive ("reassemble" being the
more expensive option, even if it's the one the vast majority of users
should be using).
Extend the 'scrub' syntax to allow fragment reassembly to be disabled,
while retaining the other scrub behaviour (e.g. TTL changes, random-id,
..) using 'scrub fragment no reassemble'.

BUS_PASS_SUPPORTDEV is semantically better than BUS_PASS_RESOURCE, since
it's a support device for dtsec, so only needs probed before dtsec, not
before interrupts.
Suggested by: manu
It's possible the MDIO device hasn't been and attached, or is incorrect
in the device tree so can't probe and attach. In this case,
ofw_bus_find_child_device_by_phandle() will fail, and return NULL.
Return an error from find_mdio() here to prevent the MAC from attaching,
rather than worry about a NULL pointer dereference later on when
accessing the PHY.
