[EP] updated description of packet injection in the doc/spec/HDL/WRS_HDL-SW_IF

the control bits were added meaning to make the injection more flexible and robust: EOF bit 16 also means SOF, user-word bit 17 also means bitsel=0 (odd size)

       The buffer layout goes as follows:\
          - the lower part (offsets 0 to 255) contains the VLAN untagged set bitmap. Each bit represents a single VLAN, where VID = OFFSET * 16 + bit position. For bits set to 1, VLAN headers containing corrensponding VID value are untagged.\
-       - the higher part (offsets 512 to 1024) contains the packet injection template buffer.         The buffer can store up to 8 packet templates of up to 128 bytes of size. Bits [15:0] of each entry contain the data value to be sent, bit 16 indicates the last word to transfer and bit 17 indicates that the current word shall be replaced by the user value (inject_user_value_i).";
