Message-Id: <20201121160902.808705-1-vlad@buslov.dev>

Subject: [PATCH net-next] net: sched: alias action flags with TCA_ACT_ prefix
Currently both filter and action flags use same "TCA_" prefix which makes
them hard to distinguish to code and confusing for users. Create aliases
for existing action flags constants with "TCA_ACT_" prefix.
