MAC Receive
If neither a hash match (group or individual) nor an exact match (group or individual) occur,
and if promiscuous mode is enabled (RCR[PROM] equals 1), the frame is accepted and the
MISS bit is set; otherwise, the frame is rejected.
This means the status bit is set in any of the following conditions during promiscuous mode:
26.3.7.5.1 Payload Length Check
If the Length / Type has a value lower than 0x600 and if the register bit NO_LGTH_CHECK
is configured to perform the check, the MAC checks the payload length and reports any
error in the frame status word (Bit 1 of Core signal ff_rx_err_stat(0) and interrupt bit PLR).
If the Length / Type field has a value greater or equal 0x600, the MAC interprets the field
as a type and no payload length check is performed.
The length check is performed on VLAN and stacked VLAN frames.
If a padded frame is received, no length check can be performed due to the extended frame
payload (that is, padded frames never can have a payload length error).
26.3.7.5.2 Frame Length Check
When the receive frame length exceeds MAX_FL bytes, the BABR interrupt bit is generated.
The LG register bit and ff_rx_err_stat(1) are set to '1'.
The frame is not truncated unless the frame length exceeds the value programmed in
TRUNC_FL. If the frame is truncated, ff_rx_err_stat(2) is set to '1'. In addition, a truncated
frame will always have the CRC error indication set (ff_rx_err_stat(3)).

• BC_REJ=1. A broadcast frame is received in promiscuous mode while broadcast reject
• A unicast is received that does not match with any of the following:
• A multicast is received that does not match the GADDR1/2 hash table entries
is set.
(GALR/IAUR)
• PADDR1/ 2 (Node address, PALR/PAUR)
• SMAC_0/1/2/3 (supplemental unicast addresses)
• IADDR1/2 hash table entries (hash table for unicast, IALR/IAUR)
