Algorithm:
- There is one master queue and one final queue to maintain the
packets.
- Final queue will start when a packet received with TTL=1
- TTL = 2 and 3 packets will be queued into final if those are in
sequence else those will be queued to master queue.
- When packet received with TTL = 2 then only merge process will start
- For every valid final queue merge starts by looking at the IPID
in master queue in increment order. This loop continues until
TTL = 2 found in master queue.
- Once TTL = 2 found then entire final queue will be given GRO
layer in sequential order.

20e4a2fb7a nvethernet: Call netif_carrier_on/off based on PHY link 
Issue: When configuring loopback mode, netif_carrier_on/off
       APIs are directly used i.e, netif_carrier_on when
       loopback mode enabled, netif_carrier_off when
       loopback mode is disabled. If anyone enables/disables
       loopback mode when link is alreay up, then link is
       not restored. Stack is not sending packets due
       to netif_carrier_off.
Fix:   Check PHY link status before calling netif_carrier_*
       APIs. If link is up, then PHY framework would have
       already invoked these APIs.
