I'm seeing a build fail at line 1878 of intel_tc.c
gcc is being a bit over-enthusiastic about snprintf() formats and reports that "%c/TC#%d", xxx, tc_port + 1 might not fit in the 8 bytes available. 'tc_port' is an enum with values -1 to 5. I guess it is either allowing for the full 'int' value of the enum. Changing to '(tc_port & 7) + 1' stops the compiler bleating.
The code isn't new, so I guess the compiler flags have changed?
It might depend on the gcc version as well. I'm using gcc 7.5.0 from Ubuntu 18.04.
