With this, we have observed delays in the order of 350ms and packets are dropped in OVS due to bond-admissibility check (packets received on slave in "disabled" state are dropped). Fix: ==== When a LACPDU is received, evaluate whether LACP slave can be enabled (slave_may_enable()) and set LACP slave's may_enable from the datapath thread itself. When may_enable = TRUE, it means L1 state is UP and LACP-SYNC is done and it is waiting for the main thread to enable the slave. Relax the check in bond_check_admissibility() to check for both "enable" and "may_enable" of the LACP slave. This would avoid dropping of packets until the main thread enables the slave from bundle_run().
