+; ZeroTier One Virtual Network Port NDIS6 Driver
+;
+; Based on the OpenVPN tap-windows6 driver version 9.21.1 git
+; commit 48f027cfca52b16b5fd23d82e6016ed8a91fc4d3.
+; See: https://github.com/OpenVPN/tap-windows6
+;
+; Modified by ZeroTier, Inc. - https://www.zerotier.com/
+;
+; (1) Comment out 'tun' functionality and related features such as DHCP
+;     emulation, since we don't use any of that. Just want straight 'tap'.
+; (2) Added custom IOCTL to enumerate L2 multicast memberships.
+; (3) Increase maximum number of multicast memberships to 128.
+; (4) Set default and max device MTU to 2800.
+; (5) Rename/rebrand driver as ZeroTier network port driver.
+;
+; Original copyright below. Modifications released under GPLv2 as well.

+; ZeroTier One Virtual Network Port NDIS6 Driver
+;
+; Based on the OpenVPN tap-windows6 driver version 9.21.1 git
+; commit 48f027cfca52b16b5fd23d82e6016ed8a91fc4d3.
+; See: https://github.com/OpenVPN/tap-windows6
+;
+; Modified by ZeroTier, Inc. - https://www.zerotier.com/
+;
+; (1) Comment out 'tun' functionality and related features such as DHCP
+;     emulation, since we don't use any of that. Just want straight 'tap'.
+; (2) Added custom IOCTL to enumerate L2 multicast memberships.
+; (3) Increase maximum number of multicast memberships to 128.
+; (4) Set default and max device MTU to 2800.
+; (5) Rename/rebrand driver as ZeroTier network port driver.
+;
+; Original copyright below. Modifications released under GPLv2 as well.

+    This is an optional function. If this handler is not specified, NDIS

+/*++
+
+Routine Description:
+
+    MiniportResetEx is a required to issue a hardware reset to the NIC
+    and/or to reset the driver's software state.
+
+    1) The miniport driver can optionally complete any pending
+        OID requests. NDIS will submit no further OID requests
+        to the miniport driver for the NIC being reset until
+        the reset operation has finished. After the reset,
+        NDIS will resubmit to the miniport driver any OID requests
+        that were pending but not completed by the miniport driver
+        before the reset.
+
+    2) A deserialized miniport driver must complete any pending send
+        operations. NDIS will not requeue pending send packets for
+        a deserialized driver since NDIS does not maintain the send
+        queue for such a driver.
+
+    3) If MiniportReset returns NDIS_STATUS_PENDING, the driver must
+        complete the original request subsequently with a call to
+        NdisMResetComplete.
+
+    MiniportReset runs at IRQL <= DISPATCH_LEVEL.

+Arguments:

+AddressingReset - If multicast or functional addressing information
+                  or the lookahead size, is changed by a reset,
+                  MiniportReset must set the variable at AddressingReset
+                  to TRUE before it returns control. This causes NDIS to

+    The net buffer will be completed by the calling routine after this
+    routine exits. So, under this design it is necessary to make a deep
+    copy of frame data in the net buffer.
+
+    This routine creates a flat buffer copy of NB frame data. This is an
+    unnecessary performance bottleneck. However, the bottleneck is probably
+    not significant or measurable except for adapters running at 1Gbps or
+    greater speeds. Since this adapter is currently running at 100Mbps this
+    defect can be ignored.

+; ZeroTier One Virtual Network Port NDIS6 Driver
+;
+; Based on the OpenVPN tap-windows6 driver version 9.21.1 git
+; commit 48f027cfca52b16b5fd23d82e6016ed8a91fc4d3.
+; See: https://github.com/OpenVPN/tap-windows6
+;
+; Modified by ZeroTier, Inc. - https://www.zerotier.com/
+;
+; (1) Comment out 'tun' functionality and related features such as DHCP
+;     emulation, since we don't use any of that. Just want straight 'tap'.
+; (2) Added custom IOCTL to enumerate L2 multicast memberships.
+; (3) Increase maximum number of multicast memberships to 128.
+; (4) Set default and max device MTU to 2800.
+; (5) Rename/rebrand driver as ZeroTier network port driver.
+;
+; Original copyright below. Modifications released under GPLv2 as well.
