arp - fixed invalid static ARP entries after reboot on interfaces without IP address bridge - general development of hw-offload bridge implementation (introduced in v6.40rc36) switch - 'master-port' conversion into a bridge with hardware offload 'hw' option (CLI only) bridge - implemented software based vlan-aware bridges wireless - added 'russia3' country settings Other changes since 6.40.1:

winbox - hide 'level' and 'tunnel' parameters for IPSec policy templates winbox - fixed bridge port sorting order by interface name winbox - do not show duplicate 'Template' parameters for filter in IPSec policy list winbox - added support fro certificate CRL list ups - fixed duplicate 'failed' UPS logs rb750gr3 - show warning and do not allow to use 'protected-bootloader' feature if 'factory-firmware' older than 3.34.4 version rb2011 - fixed possible LCD blinking along with ethernet LED (introduced in 6.40) modem - added initial support for Alcatel IK40 and Olicard 500 led - fixed 'modem-signal' LEDs (introduced in 6.40) ipsec - renamed 'firewall' argument to 'notrack-chain' in peer configuration

ipsec - allow to specify remote peer address as DNS name (CLI only) interface - fixed corrupted '/interface list' configuration after upgrade ike2 - use peer configuration address when available on empty TSi ike2 - check identities on 'initial-contact' ike1 - release mismatched PH2 peer IDs bridge - automatically turn off 'fast-forward' feature if both bridge ports have 'H' flag bridge - added initial support for hardware 'igmp-snooping' on CRS1xx/2xx (CLI only) Please, note that downgrading to previous RouterOS versions will not restore 'master-port' configuration, so use backups to restore configuration on downgrade.What's new in 6.41rc11: The rest of RouterOS Switch specific configuration remains untouched in usual menus for now. Bridge will handle all Layer2 forwarding and the use of switch-chip (hw-offload) will be automatically turned on based on appropriate conditions. This update will convert all interface 'master-port' configuration into new bridge configuration, and eliminate 'master-port' option as such.

RouterOS (v6.40rc36-rc40 and) v6.41rc1+ contains new bridge implementation that supports hardware offloading (hw-offload).
