In addition, a struct dsa_8021q_context *ctx pointer will be added to struct dsa_switch. It seems fairly low-reward to #ifdef the *ctx from struct dsa_switch and to provide shim implementations of the entire tag_8021q.c calling surface (not even clear what to do about the tag_8021q cross-chip notifiers to avoid compiling them). The runtime overhead for switches which don't use tag_8021q is fairly small because all helpers will check for ds->tag_8021q_ctx being a NULL pointer and stop there. So let's make it part of dsa_core.o. Signed-off-by: Vladimir Oltean Signed-off-by: David S.
