Yes, I was considering increasing buffer size with view of the jumbo
packets. In gem_transmit(), 'tx_desc_get_length' returns length masked by
DESC_1_LENGTH(=0x1FFF=8191) bytes. But thought dynamic allocation might lead
to excessive buffer allocation, not sure how constrained the Xilinx platform
is for memory.
