sdk-6.5.35-xgs unconditionally errors when DCBDIR is unset, which breaks the SONiC opennsl-modules deb build (debian/rules does not pass DCBDIR). sdk-6.5.34-xgs and earlier branches default DCBDIR to \/systems/linux/kernel/modules/dcb -- restore that pattern here so the SONiC build can clean/compile bcm-genl without external configuration.

Why
sdk-6.5.35-xgs unconditionally errors when
DCBDIRis unset, which breaks the SONiCopennsl-modulesdeb build becausedebian/rulesdoes not passDCBDIRto the kernel-module make invocations:Makefile:38: *** 'The $DCBDIR variable is not set'. Stop. make[5]: *** [.../Make.subdirs:40: bcm-genl] Error 2How
Restore the same path fallback that sdk-6.5.34-xgs and prior branches use:
ifndef DCBDIR / DCBDIR = $(SDK)/systems/linux/kernel/modules/dcb / endifThe
dcb/source tree exists in this branch so the fallback path is valid. No behavior change for callers that already set DCBDIR; restores buildability when it's unset.Test
CI verification on sonic-net/sonic-buildimage#27465.
