At attach, print the SCL and SDA pin numbers.
Remove a stray blank line.
Remove the GPIOBUS locking from gpioiic_reset(), it is already called with
this lock held. This fixes a crash when you try to scan the iicbus with
i2c(8).
get_scatter_segment() in get_fl_payload() fails. While here,
fix the code to adjust fl_bufs_used when a failure occurs for
any other scatter segment.

If a vt(4) font does not exactly fit the screen dimensions, the console
window is offset so that it is centered. A rectangle is drawn at the
top, left, right, and bottom of the screen, to erase any leftovers that
are outside of the new usable console area.
If the x offset or y offset is 0 then the left border or top border
respectively is not drawn. The right and bottom borders may be one
pixel larger than necessary due to rounding, and are always drawn.
Prior to this change a 0 offset would result in a panic when calling
vt_drawrect with an x or y coordinate of -1.

vt_grow may be called with a new size that's larger than previous but
does not require reallocation - for example, when the number of columns
is the same and new number of rows is less than the history size.
Prior to this change we would fail to update vb_scr_size, and then hit
a KASSERT when trying to write to the newly visible rows.

- Based on actual usage and on what Linux does, dummy_page.addr should
contain the physical bus address of the dummy page rather than its
virtual one. As a side-effect, correcting this bug fixes compilation
with PAE support enabled by getting rid of an inappropriate cast.
- Also based on actual usage of dummy_page.addr, theoretically Radeon
devices could do a maximum of 44-bit DMA. In reality, though, it is
more likely that they only support 32-bit DMA, at least that is what
radeon_gart_table_ram_alloc() sets up for, too. However, passing ~0
to drm_pci_alloc() as maxaddr parameter translates to 64-bit DMA on
amd64/64-bit machines. Thus, use BUS_SPACE_MAXSIZE_32BIT instead,
which the existing 32-bit DMA limits within the drm2 code spelled as
0xFFFFFFFF should also be changed to.

Netmap gets its own hardware-assisted virtual interface and won't take
over or disrupt the "normal" interface in any way. You can use both
simultaneously.
For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface
(note the 'n' prefix) in the hardware to accompany each cxl<N>
interface. These two ifnet's per port share the same wire but really
are separate interfaces in the hardware and software. Each gets its own
L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You
should run netmap on the 'n' interfaces only, that's what they are for.
With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port
of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now.
Single port receive is at 33Mpps but this is very much a work in
progress. I expect it to be closer to 40Mpps once done. In any case
the current effort can already saturate multiple 10G ports of a T5 card
at the smallest legal packet size. T4 gear is totally untested.

- Put "_LE_" into the register access macros to indicate little endian
byte order is expected by the hardware.
- Avoid using the bounce buffer when not strictly needed. Try to move
data directly using bus-space functions first.
- Ensure we preserve the reserved bits in the power down mode
register. Else the hardware goes into a non-recoverable state.
- Always use 32-bit access when writing or reading registers or FIFOs,
because the hardware is 32-bit oriented and don't really understand 8-
and 16-bit access.
- Correct writes to the memory address register. There is no need to
shift the register offset.
- Correct interval for interrupt endpoints.
- Optimise 90ns internal memory buffer read delay.
- Rename PDT into PTD, which is how the datasheet writes it.
- Add missing programming for activating host controller PTDs.

Idle priority is not even time-share, so if system is busy in any way,
those events may never be executed. Since in some cases system waits
for events processed by that thread, that may cause deadlocks.
