Thanks Navdeep, Now I understood that if any C file want to use a specific= 'options' (defined in the config file), then its corresponding .h file(fou= nd at sys/conf/options<arch>) needs to be included. #include "opt_bpf.h" My issue resolved after adding the above line in all C files which used BPF= _FILTER macro. Thanks, Krishna. -----Original Message----- From: Navdeep Parhar [mailto:nparhar@gmail.com] On Behalf Of Navdeep Parhar Sent: Tuesday, September 20, 2016 12:04 PM To: KrishnamRaju ErapaRaju <Krishna2@chelsio.com> Cc: Bjoern A.

If this is new code you must in= clude opt_bpf.h in it. If it's part of a module then the module's makefile= must have opt_bpf.h in its SRCS. When in doubt take a look at all the obt= _bpf.h in your obj tree after the buildkernel and see if they have "#define= BPF_JITTER 1" or not. Remove all opt_bpf.h files in the obj tree and retr= y buildkernel if all else fails.
