Currently all the network interfaces share the one recycled transmit buffer
array, which is used to store the recycled buffer address. However, those
recycled buffers are allocated by the different MNP interface if the multiple
network interfaces existed. Then, SNP GetStatus may return one recycled transmit
buffer address to the another MNP interface, which may result in the MNP driver
hang after 'reconnect -r' operation.

According to UEFI spec, the Snp.GetStatus should
return the recycled transmit buffer address, while
the NT32 SNP always return value 1 for the Txbuffer.
