PR 122928 - might be fixed by this, no verification at this point.
Change so that we save off a type field for display and
NULL inp just for good measure.
- sctp_output.c - Fix it so in sending to the loopback we use the
src address of the inbound INIT. We don't want
to do this for non local addresses since otherwise
we might be ingressed filtered so we need to use
the best src address and list the address sent to.

The patch does not change the cdevsw KBI. Management of the data is
provided by the functions
int devfs_set_cdevpriv(void *priv, cdevpriv_dtr_t dtr);
int devfs_get_cdevpriv(void **datap);
void devfs_clear_cdevpriv(void);
All of the functions are supposed to be called from the cdevsw method
contexts.
- devfs_set_cdevpriv assigns the priv as private data for the file
descriptor which is used to initiate currently performed driver
operation. dtr is the function that will be called when either the
last refernce to the file goes away, the device is destroyed or
devfs_clear_cdevpriv is called.
- devfs_get_cdevpriv is the obvious accessor.
- devfs_clear_cdevpriv allows to clear the private data for the still
open file.
Implementation keeps the driver-supplied pointers in the struct
cdev_privdata, that is referenced both from the struct file and struct
cdev, and cannot outlive any of the referee.
Man pages will be provided after the KPI stabilizes.

Directory IO without a VM object will store data in 'malloced' buffers
severely limiting caching of the data. Without this change VM objects for
directories are only created on an open() of the directory.
TODO: Inline test if VM object already exists to avoid locking/function call
overhead.

controller. L1 has several threshold/timer registers and they
seem to require careful tuned parameters to get best
performance. Datasheet for L1 is not available to open source
driver writers so age(4) focus on stability and correctness of
basic Tx/Rx operation. ATM the performance of age(4) is far from
optimal which in turn means there are mis-programmed registers or
incorrectly configured registers.
Currently age(4) supports all known hardware assistance including
- MSI support.
- TCP Segmentation Offload.
- Hardware VLAN tag insertion/stripping.
- TCP/UDP checksum offload.
- Interrupt moderation.
- Hardware statistics counter support.
- Jumbo frame support.
- WOL support.
L1 gigabit ethernet controller is mainly found on ASUS
motherboards. Note, it seems that there are other variants of
hardware as known as L2(Fast ethernet) and newer gigabit ethernet
(AR81xx) from Atheros. These are not supported by age(4) and
requires a seperate driver. Big thanks to all people who reported
feedback or tested patches.

superpage-aligned virtual address for the mapping. Revision 1.65
implemented an overly simplistic and generally ineffectual method for
finding a superpage-aligned virtual address. Specifically, it rounds
the virtual address corresponding to the end of the data segment up to
the next superpage-aligned virtual address. If this virtual address
is unallocated, then the device will be mapped using superpages.
Unfortunately, in modern times, where applications like the X server
dynamically load much of their code, this virtual address is already
allocated. In such cases, mmap(2) simply uses the first available
virtual address, which is not necessarily superpage aligned.
This revision changes mmap(2) to use a more robust method,
specifically, the VMFS_ALIGNED_SPACE option that is now implemented by
vm_map_find().
physical address of the device's memory. This enables
pmap_align_superpage() to propose a virtual address for mapping the
device memory that permits the use of superpage mappings.
- verified that the ifp->if_snd.ifq_mtx was initalized for
all attached interfaces. This was pointless because it was
initalized for all interfaces in if_attach() so I've removed it.
- Checked that ifp->if_snd.ifq_maxlen is initalized and set it to
ifqmaxlen if unset. This makes more sense in if_attach() so
I moved it there.
