- Add code allowing a network device to only be open and closed once by keeping it opened after the first open and closing it via the cleanup handler when NETIF_OPEN_CLOSE_ONCE is defined in order to avoid the open-close-dance on every file access which with firmware that for example performs an auto-negotiation on every open causes netbooting to take horribly long. Basically the behavior with this knob enabled resembles the one employed between r60506 and r177108 (and for sparc64 also again since r182919) with the addition that the network device now is closed eventually before entering the kernel and before rebooting. Actually I think this should be the desired MI behavior, however the U-Boot loader actually requires net_close() to be called after every transaction in order for some local shutdown operations to be performed (and which I think thus will break on concurrent opens, i.e. when netdev_opens is > 1, like the loader does at least for disks when LOADER_GZIP_SUPPORT is enabled). - Use NETIF_OPEN_CLOSE_ONCE to replace the hack, which artificially increased netdev_opens for sparc64 in order to keep the network device opened forever, as at least some firmware versions require the network device to be closed eventually before entering the kernel or otherwise will DMA received packets to stale memory. The powerpc OFW loader probably wants NETIF_OPEN_CLOSE_ONCE to be set as well for the same reasons.

Remove clause 3 and 4 from TNF licenses (this was the only 4-clause TNF license FreeBSD had in sys/boot). Obtained from: NetBSD

- Consistently wrap debugging in NETIF_DEBUG. This basically merges NetBSD rev 1.19. - Make the functions match their prototypes regarding static.

Revert r177108 and restore r60506 for sparc64 as long as libstand

isn't fixed to only open the network device once and not do a open and close dance on every file access; the firmwares of newer sparc64 machines perform an auto-negotiation with every open which in turn causes netbooting to take horribly long if we open and close the device over and over again.

Show info about net devices in loader's 'lsdev' command. While there fix style.

Eliminate artificial increasing of 'netdev_opens' counter in loader's net_open().

This was introduced as a workaround long time ago for some Alpha firmware (which is now gone), and actually prevented net_close() to ever be called. Certain firmwares (U-Boot) need local shutdown operations to be performed on a network controller upon transaction end: such platform-specific hooks are supposed to be called via netif_close() (from within net_close()). This change effectively reverts the following CVS commit: sys/boot/common/dev_net.c revision 1.7 date: 2000/05/13 15:40:46; author: dfr; state: Exp; lines: +2 -1 Only probe network settings on the first open of the network device. The alpha firmware takes a seriously long time to open the network device the first time. Also suppress excessive output while netbooting via loader, unless debugging. While there, make sys/boot/uboot more style(9) compliant. Reviewed by: imp Approved by: cognet (mentor)

Change the following environment variables to kernel options:

BOOTP -> bootp BOOTP_NFSROOT -> bootp.nfsroot BOOTP_NFSV3 -> bootp.nfsv3 BOOTP_COMPAT -> bootp.compat BOOTP_WIRED_TO -> bootp.wired_to This lets you PXE boot with a GENERIC kernel by putting this sort of thing in loader.conf: bootp="YES" bootp.nfsroot="YES" bootp.nfsv3="YES" bootp.wired_to="bge1" or even setting the variables manually from the OK prompt.
