++ first). The kernels on both machines need to have this PLIP option

++ in the PPP-HOWTO, available at

++ the version of pppd recommended in <file:Documentation/Changes>.
++ The PPP option enlarges your kernel by about 16 KB.
++
++ There are actually two versions of PPP: the traditional PPP for
++ asynchronous lines, such as regular analog phone lines, and
++ synchronous PPP which can be used over digital ISDN lines for
++ example. If you want to use PPP over phone lines or other
++ asynchronous serial lines, you need to say Y (or M) here and also to

++
++ If you said Y to "Version information on all symbols" above, then

++ Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to

++ * EHCI hc_driver implementation ... experimental, incomplete.
++ * Based on the final 1.0 register interface specification.
++ *
++ * USB 2.0 shows up in upcoming www.pcmcia.org technology.
++ * First was PCMCIA, like ISA; then CardBus, which is PCI.
++ * Next comes "CardBay", using USB 2.0 signals.
++ *
++ * Contains additional contributions by Brad Hards, Rory Bolt, and others.
++ * Special thanks to Intel and VIA for providing host controllers to
++ * test this driver on, and Cypress (including In-System Design) for
++ * providing early devices for those host controllers to talk to!
++ *
++ * HISTORY:
++ *
++ * 2004-05-10 Root hub and PCI suspend/resume support; remote wakeup. (db)
++ * 2004-02-24 Replace pci_* with generic dma_* API calls (dsaxena@plexity.net)
++ * 2003-12-29 Rewritten high speed iso transfer support (by Michal Sojka,
++ * <sojkam@centrum.cz>, updates by DB).
++ *
++ * 2002-11-29 Correct handling for hw async_next register.
++ * 2002-08-06 Handling for bulk and interrupt transfers is mostly shared;
++ * only scheduling is different, no arbitrary limitations.
++ * 2002-07-25 Sanity check PCI reads, mostly for better cardbus support,
++ * clean up HC run state handshaking.
++ * 2002-05-24 Preliminary FS/LS interrupts, using scheduling shortcuts
++ * 2002-05-11 Clear TT errors for FS/LS ctrl/bulk. Fill in some other
++ * missing pieces: enabling 64bit dma, handoff from BIOS/SMM.
++ * 2002-05-07 Some error path cleanups to report better errors; wmb();
++ * use non-CVS version id; better iso bandwidth claim.
++ * 2002-04-19 Control/bulk/interrupt submit no longer uses giveback() on
++ * errors in submit path. Bugfixes to interrupt scheduling/processing.
++ * 2002-03-05 Initial high-speed ISO support; reduce ITD memory; shift
++ * more checking to generic hcd framework (db). Make it work with
++ * Philips EHCI; reduce PCI traffic; shorten IRQ path (Rory Bolt).
++ * 2002-01-14 Minor cleanup; version synch.
++ * 2002-01-08 Fix roothub handoff of FS/LS to companion controllers.
++ * 2002-01-04 Control/Bulk queuing behaves.
++ *
++ * 2001-12-12 Initial patch version for Linux 2.5.1 kernel.
++ * 2001-June Works with usb-storage and NEC EHCI on 2.4
