I'm planning on checking in the zero copy sockets code Tuesday evening,
MDT. If there are any concerns, I'm more than willing to delay it.
I've also released a new snapshot, based on -current from June 23rd, 2002:
The following changes went into this snapshot:
- Added a zero_copy(9) man page that describes the general characteristics
of the zero copy send and receive code, and what an application author
should do to take advantage of the code.
- Update the ti(4) man page to include information on the ioctl interface
and the TI_JUMBO_HDRSPLIT and TI_PRIVATE_JUMBOS kernel options.
- Added information to NOTES about the ZERO_COPY_SOCKETS, TI_PRIVATE_JUMBOS,
TI_JUMBO_HDRSPLIT, MSIZE and MCLSHIFT kernel config options.
- ti(4) driver cleanup: cleaned up some unused code, commented out some
stray diagnostic printfs, and added a problem describing the transmit
flow control problem for posterity.
- Added a new jumbo(9) man page that describes the jumbo allocator.
I haven't run this through the usual array of regression tests just yet,
but that will be done before checkin.
(I used the time to run through a buildworld and a LINT build instead.)
Feedback and comments are welcome.
Again, if there are any concerns, I'm more than willing to delay the
