NIC card repetative Failover
I have configure 2 NIC in ipmp group1 .Similarly other 2 NIC in ipmp group2
When I connect both NIC to 2 different switch , which is connect to one L3 switch as trunk. Both the NIC failover to each other continously.
Following are the message log.

chxge(7D) Devices chxge(7D)
NAME
chxge - Chelsio Ethernet network interface controllers
SYNOPSIS
/dev/chxge
DESCRIPTION
The chxge Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link
Provider Interface, dlpi(7P), over Chelsio NIC controllers. Multiple (and mixed) NIC controllers installed within the system are sup-
ported by the driver. The chxge driver provides basic support for the NIC hardware. Functions include chip initialization, frame transmit
and receive, and error recovery and reporting.
APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/chxge is used to access NIC devices installed within the system.
CHXGE AND DLPI
The chxge driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the chxge driver with the DLPI and STREAMS
functionality required of a LAN driver. See gld(7D) for more details on the primitives supported by the driver.
The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ are:
o Default Maximum SDU is 1500 (ETHERMTU).
o dlsap address length is 8.
o MAC type is DL_ETHER.
o The sap length value is -2, meaning the physical address component is followed immediately by a 2-byte sap component within
the DLSAP address.
o Broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
