Second pass at BOOTP/DHCP rewrite.
Comments are welcome on the second pass at the BOOTP/DHCP rewrite.
Changes from the first pass are:
1) Miscellaneous cleanup.
2) Fixed DHCP support so that it works in "fall-back" mode if the
server only does plain BOOTP and not DHCP.
3) Created new option CYGPKG_REDBOOT_NETWORKING_BOOTP (default 1)
which controls whether or not BOOTP/DHCP support (src/net/bootp.c)
is built. This new package contains the sub-options:
CYGSEM_REDBOOT_NETWORKING_DHCP (default 1)
CYGSEM_REDBOOT_NETWORKING_BOOTP_VERBOSE (default 0)
CYGSEM_REDBOOT_DEFAULT_NO_BOOTP (default 0)
That last one used to be contained in CYGDAT_REDBOOT_DEFAULT_IP_ADDR.
Building with no BOOTP-related options specified should result in
the same behavior as previously.
I've done test builds for i386 PC platform with all combinations of
"absent/0/1" for the following:
CYGPKG_REDBOOT_NETWORKING_BOOTP
CYGSEM_REDBOOT_DEFAULT_NO_BOOTP
CYGSEM_REDBOOT_NETWORKING_DHCP
CYGSEM_REDBOOT_NETWORKING_BOOTP_VERBOSE
CYGDAT_REDBOOT_DEFAULT_IP_ADDR
About a dozen of the combinations have been tested with both DHCP and
BOOTP-only servers.
One thing I don't have the ability to test is flash-config support, so
it wouldn't hurt if somebody took a look at that. I tried building
for the i386 PC platform with CYGSEM_REDBOOT_FLASH_CONFIG enabled, but
that didn't work.
