The netmap application using the driver is responsible for replenishing
the receive freelists and they may be totally depleted when the
application exits. Packets in flight, if any, might block the pipeline
in case there aren't enough buffers left in the freelist. Avoid this by
filling up the freelists with a driver allocated buffer.

Recent commits to head have added support for NFS over TLS
to the FreeBSD kernel.
To enable use of this for an NFS mount, the "tls" mount_nfs
option has been added.
Once the IETF has assigned an RFC number, I will replace "NNNN"
with the number.
This is a content change.

NFS over TLS uses three new export options, added by r364979.
This patch updates the exports.5 man page for these new options.

Qlogic chips store S/G lists in the same queue as requests themselves. In
the worst case 1MB I/O may require up to 52 IOCBs, that means queue of 1024
IOCBs can store only 19 of such requests. The increase reduces chances of
overflow, while we should be able to afford additional 512KB of RAM per HBA.
The Linux driver uses comparable numbers.
While there, decouple ATIO queue size from response queue size. There is
no reason for them to be equal.

- Make isp_start() to set all the IOCB fields aside of S/G list, removing
extra information from isp_send_cmd(), now only doing S/G lists and sending.
- Turn DMA setup/free from being card and PCI-specific into OS-specific,
instead add new card-specific method for isp_send_cmd(). Previously this
function was a monster handling all the cards.
- Remove double error code translation.
encode 0-length (i.e. "") structure and union member names as offset 0.
This ensures that we don't confuse other parts of the CTF code which
expect this encoding.
This resolves a Dtrace error resolving members of anonymous structs/unions
within the (struct mbuf) type which some users were seeing after r366908.
While here, update the code in ctf_add_generic() to encode 0-length type
names as offset 0.

Ensure we initialize the static environment when not booting via
loader(8), and provide a static buffer if this is the case. This fixes
two issues.
First, performing the initialization ensures that kenv variables set in
the kernel's config file are honored. Previously, any new or overridden
values were ignored.
Second, providing the static buffer allows variables to be set in the
device tree's bootargs property of the chosen node. This can be set by
u-boot or by QEMU's '-append' flag. Attempting to this prior to this
change resulted in an early panic, since the static environment had no
buffer backing it.

Don't use "new" as an identifier, and add explicit casts from void *.
As a general policy, FreeBSD doesn't make any C++ compatibility
guarantees for kernel headers like it does for userland, but it is a
small effort to do so in this case, to the benefit of a downstream
consumer (NetApp).

The problem is that zfs is asked to stop too early in the shutdown
sequence. Other services, such as syslog may still be running and have some
files open (e.g., under /var/log). This of course causes the messages like:
cannot unmount '/var/run': umount failed
cannot unmount '/var/log': umount failed
cannot unmount '/var': umount failed
cannot unmount '/usr/home': umount failed
cannot unmount '/usr': umount failed
cannot unmount '/': umount failed
For now, let's remove the shutdown KEYWORD from the zfs service, as people are
reporting problems in their setups:
https://lists.freebsd.org/pipermail/freebsd-current/2020-November/077559.html
In the future, we may think of stopping zfs on shutdown after all the other
services and just before init(8) exits. Another interesting option might be to
a new rcorder(8) KEYWORD like "shutdownjail", but this idea would need to be
discussed a bit.
