mstp: use default Hello Time in recordTimes

2026-05-27T11:26:50Z

802.1Q-2011 says recordTimes should set Hello Time to the default. Follow that instead of preserving the local configured Hello Time. This fixes received information aging when the local bridge uses a shorter Hello Time than its neighbor. With OpenWrt's hello_time=1 and a Huawei S6720 sending RSTP BPDUs every 2 seconds, rcvdInfoWhile was set to 3 seconds. With normal scheduling jitter, the superior information could expire before the next BPDU, causing ustp to briefly elect itself root and send a self-root BPDU. On a realtek Edgecore ECS4100-12PH, this caused repeated MSTP PACKET_ERR_COMPLIAN errors on the Huawei side, together with brief forwarding -> discarding -> forwarding state changes: May 13 2026 16:31:22+03:00 DST cs0 %%01MSTP/3/PACKET_ERR_COMPLIAN(l)[47259]:The port compliance protocol type of the packet received by MSTP from the port XGigabitEthernet0/0/3,(InsId:0,RcvInt:0,SrcMAC:fa8e-a111-a57f,RootId:32768.f88e-a111-a574,ExCost:0,BdgId:32768.f88e-a111-a574,PortId:128.10,RegRootId:0.0000-0000-0000,InCost:0) is invalid.

There were 2396 errors between 2026-05-01 and 2026-05-19 10:00 with one OpenWrt realtek switch running STP. After deploying this fix on two Edgecore ECS4100-12PH switches, both running OpenWrt + ustp and connected to the same Huawei, there were zero errors for 8 days.

mstp: add default Hello Time constant

2026-05-27T11:21:34Z

The default Hello Time is used when initializing a bridge. Add a constant for it instead of hard-coding the value. This will be reused in the next commit to follow the 802.1Q-2011 recordTimes behavior. Signed-off-by: Stijn Tintel
