txgbe-2.1.1.3(release time:2025/09/26)
[Bug]
- optimize delayed-releasing tx skbs/buffers mechanism. [jira:AMLITE-390]
  [Impact scenarios]: 
  Some applications like pktgen, which require memory reuse, need driver to release tx skb as soon as possible.
  [severity]: middle
 
- fix bug that command "lldptool -T -i dev PFC enable=1,2,4" takes no effect. [AMLITE-431]
  [Impact scenarios]: 
  After executing "lldptool -T -i dev PFC enable=1,2,4" to enable Priority Flow Control (PFC) on priority levels 1,2 and 4,
  receving the pfc packets on priority level 0 would still cause the port traffic reduction.
  [severity]: middle

- fix bug that vf multicast address removal takes no effect. [EMERALDSW-380]
  [Impact scenarios]:
  VF continues receving traffic with removed mulicast addresses.
  [severity: high] 
  
- fix bug that bond port speed rate shows unknown while link shows up under some special condition. [AMLITE-420]
  [Impact scenarios]:
  Create a bond on 25G card ports with dual-speed(25G/10G) optical module and connect them to a 10G switch,
  After restarting the device, the physical port speed is normal, but the bond port speed rate is unknown.
  [severity: low]
  
- fix bug of the statistics on rx pfc xon/xoff [AMLITE-429]
  [Impact scenarios]:
  After executing "lldptool -T -i dev PFC enable=1,2,4" to enable Priority Flow Control (PFC) on priority levels 1,2 and 4,
  and receving some pfc packets on priority level 1,  the statistic value of rx_pb_n_pxoff1(shows in ethtool -S) which is used to 
  count the recevied pfc packets on priority level 1 is still zero.  
  [severity: middle]

- fix bug that dma reset works abnormally. 
  [Impact scenarios]:
  When there's tx transmit queue timeout, the driver will initiate a dma reset. This bug may cause the reset to be called recursively and 
  cannot end up.
  [severity: high]

- fix bug that command "ethtool -m" would return -EINVAL on SP1000/RP2000 card when a DAC cable is plugged in.
  [Impact scenarios]:
  command "ethtool -m" would return -EINVAL when a DAC cable is plugged in.
  [severity: low]

  Change the minimum tx ring depth to 512 on 25G/40G card while 256 on 10G card. 
  [Impact scenarios]:
  setting tx ring depth to 128 by "ethtool -g ethx tx 128" would cause tx queue transmit timeout. 
  [severity: high]

- fix bug that there's call trace shows that double free WARN and/or a BUG in free_msi_irqs().
  [Impact scenarios]:
  when pcie hot reset flow and "ifconfig down" or xdp_setup are running at the same time, there's call trace
  printed out waring that double free irq. 
  [severity: high]
  
- fix some fec configuration related bugs on 25G/40G card.[AMLITE-460,463,469]
  [severity: middle]

- fix bug that after enabling sriov firstly and pf promisc mode secondly, and then set vlan port over pf port, 
  the pf port dropped the unmatched vlan id packets.[AMLITE-464]
  [Impact scenarios]:
  executing following commands in sequence:
  echo 1>/sys/class/net/enp25s0f0/device/sriov numvfs
  ip link set dev enp25s0f0 vf 0 trust on
  ifconfig enp25s0f0 promisc
  ip link add link enp25s0f0 name enp25s0f0.101 type vlan id 101
 
  the pf port would drop the vlan packcets with mismatched vlan id. For example, it would drop the packet with vlan 100. 
  [severity: middle]

- fix bug that i2c access to sfp module eeprom would ocasionally fail after repeatedly down/up port.
  [Impact scenarios]:
  when repeatedly excecuting "ethtool -a" or "ethtool -A", the advertised link modes cannot show correctly for dual speed sfp module. 
  [severity: middle]
