For proper operation it is required to enable ESW and MAC table lookup clocks. The MAC table spans from 0x400E_C000 for 0x4000 and it is necessary to provide clocks for each AIPS1-"slot", which size is 0x1000 (hence four separate entries). Those can be enabled via clock gating CCM_CCGR10 register (0x4006_B068).
