The safe max frame size for this ethernet switch is 1532 bytes,
excluding the DSA TAG and extra VLAN header, so the maximum
outgoing frame is 1542 bytes.
The available overhead is needed when using the DSA switch with
a cascaded Marvell DSA switch, which is something that exist in
real products, in this case the Inteno XG6846.
Use defines at the top of the size for max MTU so it is clear how
we think about this, add comments.
We need to adjust the RX buffer size to fit the new max frame size,
which is 1542 when the DSA tag (6 bytes) and VLAN header (4 extra
bytes) is added.
We also drop this default MTU:
#define ENETSW_TAG_SIZE (6 + VLAN_HLEN)
ndev->mtu = ETH_DATA_LEN + ENETSW_TAG_SIZE;
in favor of just:
ndev->mtu = ETH_DATA_LEN;
I don't know why the default MTU is trying to second guess the
overhead required by DSA and VLAN but the framework will also
try to bump the MTU for e.g. DSA tags, and the VLAN overhead is
not supposed to be included in the MTU, so this is clearly not
right.
Before this patch (on the lan1 DSA port in this case):
dsa_slave_change_mtu: master->max_mtu = 9724, dev->max_mtu = 10218, DSA overhead = 8
dsa_slave_change_mtu: master = extsw, dev = lan1
dsa_slave_change_mtu: master->max_mtu = 1510, dev->max_mtu = 9724, DSA overhead = 6
dsa_slave_change_mtu: master = eth0, dev = extsw
dsa_slave_change_mtu new_master_mtu 1514 > mtu_limit 1510
mdio_mux-0.1:00: nonfatal error -34 setting MTU to 1500 on port 0
My added debug prints before the nonfatal error: the first switch from the top
is the Marvell switch, the second in the bcm6368-enetsw with its 1510 limit.
After this patch the error is gone.
OpenWrt adds a VLAN to each port so we get VLAN tags on all frames. On this
setup we even have 4 more bytes left after the two DSA tags and VLAN so
we can go all the way up to 1532 as MTU.
Testing the new 1532 MTU:
eth0 ext1 enp7s0
.--------. .-----------. cable .------.
| enetsw | <-> | mv88e6152 | <-----> | host |
`--------´ `-----------´ `------´
On the router we set the max MTU for test:
ifconfig eth0 mtu 1520
ifconfig br-wan mtu 1520
ifconfig ext1 mtu 1506
An MTU of 1506 on ext1 is a logic consequence of the above setup:
this is the max bytes actually transferred. The framing added will be:
- 18 bytes standard ethernet header
- 4 bytes VLAN header
- 6 bytes DSA tag for enetsw
- 8 bytes DSA tag for mv88e6152
Sum: 1506 + 18 + 4 + 6 + 8 = 1542 which is out max frame size.
Test pinging from host:
ping -s 1478 -M do 192.168.1.220
PING 192.168.1.220 (192.168.1.220) 1478(1506) bytes of data.
1486 bytes from 192.168.1.220: icmp_seq=1 ttl=64 time=0.696 ms
1486 bytes from 192.168.1.220: icmp_seq=2 ttl=64 time=0.615 ms
Test pinging from router:
PING 192.168.1.2 (192.168.1.2): 1478 data bytes
1486 bytes from 192.168.1.2: seq=0 ttl=64 time=0.931 ms
1486 bytes from 192.168.1.2: seq=1 ttl=64 time=0.810 ms
The max IP packet without headers is 1478, the outgoing ICMP packet is
1506 bytes. Then the DSA, VLAN and ethernet overhead is added.
Let us verify the contents of the resulting ethernet frame of 1542 bytes.
Ping packet on router side as viewed with tcpdump:
00:54:51.900869 AF Unknown (1429722180), length 1538:

- 3d93 = First four bytes are the last two bytes of the destination
ethernet address I don't know why the first four are missing,
but it sure explains why the paket is 1538 bytes and not 1542
which is the actual max frame size.
- bcae c56b a83b = source ethernet address
- 8874 0300 0004 = Broadcom enetsw DSA tag
- 8100 0000 = VLAN 802.1Q header
- dada 0000 c020 0fff = EDSA tag for the Marvell (outer) switch,
- 0800 is the ethertype (part of the EDSA tag technically)
- Next follows the contents of the ping packet as it appears if
we dump it on the DSA interface such as tcpdump -i lan1
etc, there we get the stripped out packet, 1506 bytes.
- At the end 4 bytes of FCS.
This clearly illustrates that the DSA tag is included in the MTU
which we set up in Linux, but the VLAN tag and ethernet headers and
checksum is not.

Some of devices in this target have only 8 MiB space and are closing to
borders of usable space. Particularly, TP-Link RE305 v1 already suffers
from this issue[1], where with current partition layout, on release
images, there's not enough space for overlay. So activate small_flash
feature, which will remove some userspace hardening but will gain almost
1 MiB additional flash memory space. Here is small size comparison of
similar device (RE365 v1) with default config + LuCI:

The GCC option -fstack-protector-all is a security feature used to protect against stack-smashing attacks.
This option enhances the stack-smashing protection provided by -fstack-protector-strong.
-fstack-protector-all option applies stack protection to all functions, regardless of their characteristics.
While this offers the most comprehensive protection against stack-smashing attacks, it can significantly impact
the performance of the program because every function call includes additional checks for stack integrity.
This option can incur a performance penalty because of the extra checks added to every function call,
but it significantly enhances security, making it harder for attackers to exploit buffer overflows to execute arbitrary code.
It's particularly useful in scenarios where security is paramount and performance trade-offs are acceptable.
