the pwm values. We can now set the fan's speed of a PWM controlled fan
with % numbers between 30 and 100 % instead of trying to model a
% number based on rpm.
The fcu chip offers both, the dutycycle and the rpm value of the PWM
controlled fans. I added the rpm value to the list of information
available via sysctl(8).

and just show old (cached) values. Controller will not respond to
the command unless MAC is enabled so DUMP request for down
interface caused request timeout.
RealTek changed TX descriptor format for later controllers so these
controllers require MSS configuration in different location of TX
descriptor. TSO is enabled by default for controllers that use new
descriptor format.
For old controllers, TSO is still disabled by default due to broken
frames under certain conditions but users can enable it.

These controllers consist of two Marvell 88SE9128 6Gbps SATA chips and
PLX PCIe bridge. As result, they seem to be agree to work with ahci(4)
as usual HBAs. The only noticed issue is that RAID BIOS disables all
drive caches during boot, though `camcontrol cmd ...` is able to fix that.
Those who wants RAID functionality can still use closed proprietary driver

erroneously, assumed that 4 bytes of data were in the first
mbuf of a list by replacing the bcopy() with m_copydata().
Also, replace the uses of m_pullup(), which can fail for
reasons other than not enough data, with m_copydata().
For the cases where it isn't known that there is enough
data in the mbuf list, check first via m_len and m_length().
This is believed to fix a problem reported by dpd at dpdtech.com
and george+freebsd at m5p.com.

DMA boundary bug and runs with PCI-X mode. watchdog timeout was
observed on BCM5704 which lives behind certain PCI-X bridge(e.g.
AMD 8131 PCI-X bridge). It's still not clear whether the root
cause came from that PCI-X bridge or not. The watchdog timeout
indicates the issue is in TX path. If the bridge reorders TX
mailbox write accesses it would generate all kinds of problems but
I'm not sure. This should be revisited.

o) Add a cvmx_mgmt_port_sendm routine to the Simple Executive to send an mbuf

copy the mbuf to an intermediate buffer and then copy that to the Simple
Executive's transmit ring.

this is sufficient for now. Media detection will be fixed in the future

quite awful, because e.g. 4 packets will come in and get processed on 4
different cores at the same time, really battling with the TCP stack quite
painfully. For now, just run one task at a time.
This gets performance up in most cases to where it was before the correctness
fixes that got interrupts to run on all cores (except in high-load TCP transmit
cases where all we're handling receive for is ACKs) and in some cases it's
better now. What would be ideal would be to use a more advanced interrupt
mitigation strategy and possibly to use different workqueue groups per port for
multi-port systems, and so on, but this is a fine stopgap.

actually a clone of pjd@'s nfs_serv.c.4.patch instead of

elements that get used for the modified functions from int to uint32_t,
since it's not clear what userspace programs use these fields, and we
