RMON counters. Affected counters include TRMGV, RMCA, RBCA, RXCF,
RXPF, RXUO, RALN, RFLR, ROVR, RJBR, TMCA, TBCA, TXPF, TXCF.
Removed register sections (and memory map rows) from MPC8313 product
which only have a 32-bit address space.
In Table 15-32, add the following note to RCTRL[VLEX] and RCTRL[PRSDEP]:
If PRSDEP is cleared, VLEX must be cleared as well. (VLAN tag extraction is
only supported when the parser is enabled.)
In Table 15-32, add the following note to RCTRL[FILREN] and
RCTRL[PRSDEP]:
If PRSDEP is cleared, FILREN must be cleared as well.
Changed first sentence of RCTRL[PRSDEP] setting 00 to;
Parser disabled. Receive frame filer must also be disabled by clearing
RCTRL[FILREN].
Changed RCTRL[FILREN] description (but not bit settings) to the following:
Filer enable, when set, the receive frame filer is enabled. This will file accepted
frames to a particular RxBD ring according to rules defined in the filer table. In
this case, PRSDEP must not be cleared.
Updated register to show that they are w1c (all fields).
Added note to RQFPR[ETY].
In Table 15-39, added the following note for bit TOS:
IPv6 the Traffic Class field is extracted using the IP header definition in RFC
2460. IPv6 headers formed using the earlier RFC 1883 have a different format and
must be handled with software.
Removed register sections (and memory map rows) from MPC8313 product
which only have a 32-bit address space.Using the filer to match ETY does not
work in the case of PPPoe packets, because the PPPoe ethertype in the original
packet, 0x8864, is always overwritten with the PPP protocol field. thus, matches
on ETY == 0x8864 always fail, Instead, software should use PID=1 fields
IP4(ETy = 0x0021) and IP6 (ETY = 0x0057) to distinguish PPPoe session packets
carrying IPv4 and IPv6 datagrams. Other PPP protocols are encoded in the ETY
field, but many of them overlap with real ethertype definitions. Consult IANA and
IEEE for possible ambiguities.
In Table 15-47, added cross-reference to buffer descriptors section to description
of MACCFG2[Huge Frame].
Added the following note to section, Maximum Frame Length Register
(MAXFRM):
If MACCFG[Huge Frame] = 0, the value of this field must be less than or equal
to MRBLR[MRBL] x (minimum number of RxBDs per ring). See Section
15.5.3.6.2, "MAC Configuration 2 Register (MACCFG2)," Section 15.5.3.4.9,
