net/bnxt: support set MTU
This patch adds support to modify MTU using the set_mtu dev_op. To support frames > 2k, the PMD creates an aggregator ring. When a frame greater than 2k is received, it is fragmented and the resulting fragments are DMA'ed to the aggregator ring. Now the driver can support jumbo frames upto 9500 bytes.
