The RX flowid programming initializes the TCAM mask to all ones, but then overwrites it when clearing the MAC DA mask bits. This results in losing the intended initialization and may affect other match fields. Update the code to clear the MAC DA bits using an AND operation, making the handling of mask[0] consistent with mask[1], where the field-specific bits are cleared after initializing the mask to ~0ULL.
