/dev/igb2 as well as /dev/igb0, both shows all below supported values and I tried changing from half duplex to full duplex, but igb2 still shows down and standby.

There are multiple gateways on this server. Concerned gateway is not pingable and that is going via aggr50001
Code:
# traceroute 172.31.12.1
traceroute: Warning: Multiple interfaces found; using 172.31.12.20 @ aggr50001
traceroute to 172.31.12.1 (172.31.12.1), 30 hops max, 40 byte packets

enum_ieee80211_ampdu_mlme_action

ENUM 
IEEE80211_AMPDU(9) 				     Advanced driver interface					   ENUM IEEE80211_AMPDU(9)

NAME

       enum_ieee80211_ampdu_mlme_action - A-MPDU actions

SYNOPSIS

       enum ieee80211_ampdu_mlme_action {
	 IEEE80211_AMPDU_RX_START,
	 IEEE80211_AMPDU_RX_STOP,
	 IEEE80211_AMPDU_TX_START,
	 IEEE80211_AMPDU_TX_STOP_CONT,
	 IEEE80211_AMPDU_TX_STOP_FLUSH,
	 IEEE80211_AMPDU_TX_STOP_FLUSH_CONT,
	 IEEE80211_AMPDU_TX_OPERATIONAL
       };

CONSTANTS

       IEEE80211_AMPDU_RX_START
	   start RX aggregation

       IEEE80211_AMPDU_RX_STOP
	   stop RX aggregation

       IEEE80211_AMPDU_TX_START
	   start TX aggregation

       IEEE80211_AMPDU_TX_STOP_CONT
	   stop TX aggregation but continue transmitting queued packets, now unaggregated. After all packets are transmitted the driver has to
	   call ieee80211_stop_tx_ba_cb_irqsafe.

       IEEE80211_AMPDU_TX_STOP_FLUSH
	   stop TX aggregation and flush all packets, called when the station is removed. There's no need or reason to call
	   ieee80211_stop_tx_ba_cb_irqsafe in this case as mac80211 assumes the session is gone and removes the station.

       IEEE80211_AMPDU_TX_STOP_FLUSH_CONT
	   called when TX aggregation is stopped but the driver hasn't called ieee80211_stop_tx_ba_cb_irqsafe yet and now the connection is
	   dropped and the station will be removed. Drivers should clean up and drop remaining packets when this is called.

       IEEE80211_AMPDU_TX_OPERATIONAL
	   TX aggregation has become operational

DESCRIPTION

       These flags are used with the ampdu_action callback in struct ieee80211_ops to indicate which action is needed.

       Note that drivers MUST be able to deal with a TX aggregation session being stopped even before they OK'ed starting it by calling
       ieee80211_start_tx_ba_cb_irqsafe, because the peer might receive the addBA frame and send a delBA right away!
