net: Add SIOCGI2CPB ioctl & add page/bank fields to ifi2creq
This commit adds page & bank fields to ifi2creq in preparation
for adding CMIS support for 400g optics to ifconfig.
The new ioctl SIOCGI2CPB is added, so that drivers can distinguish
between callers asking for page/bank selection and legacy callers
that simply failed to zero out all ifi2creq fields.
The mlx5en(4) driver and iflib(4) driver frameork have been updated
to use this new SIOCGI2CPB ioctl and support page/bank operations.
A follow-on patchset will add support to ifconfig for reporting
data from CMIS optics.
This has been tested on Nvidia ConnectX-7 and Broadcom Thor2 (using
out of tree driver) based NICs.

nfs_diskless: Add support for an NFSv4 root fs
Without this patch, diskless root NFS file systems
could only be mounted via NFSv3 (or NFSv2).
This patch adds the basic support needed to mount
a root fs via NFSv4.
At this time, the NFSv4 mount will only work if
the following is done on the NFS server configuration:
- The root directory specified in the "V4:" line in
/etc/exports must be "/". This is needed since the
path to mount must be the same for NFSv3 and NFSv4.
- The NFS server must be configured to do both NFSv3
and NFSv4, since the bootstrap code still uses NFSv3.
- The NFSv4 server must be configured with:
vfs.nfs.enable_uidtostring=1
vfs.nfsd.enable_stringtouid=1
since the NFSv4 root fs cannot be running nfsuserd(8)
when it is booting. (This limitation may be removed

Fix nooptions VIMAGE build
The recent FIBify commits deref struct thread without including
sys/proc.h, which can result in a compiler error. This becomes
apparent when building with LINT-NOVIMAGE, as net/vnet.h includes
sys/proc.h. Fix this by directly including sys/proc.h

lib/msun: Added fmaximum and fminimum family. Tests and man page
Starting from the existing fmax{,f,l} functions I've added the fmaximum
family, which handles NaN according to the newest standard (propagating
it).

virtio: use modern mode for transitional device by default
This patch changes the default value of the loader tunable
hw.virtio.pci.transitional to 1. This means, virtio uses the
modern mode for transitional devices by default.
The return values of vtpci_modern_probe() and vtpci_legacy_probei()
were chosen to prefer modern mode, but hw.virtio.pci.transitional=0
prevents modern mode.
Setting hw.virtio.pci.transitional to 1 by default seems a better fit.

dpaa2: Perform bus_dma pre-write sync before enqueue operation
Without a proper synchronization payload of the egress TCP segments

This patch is indirectly related to 292006 because a properly enabled
