[dpdk-dev] [PATCH v3] testpmd: add speed capability in device info

[Sarosh Arif <sarosh.arif@emumba.com>]

Called rte_eth_dev_info_get() in testpmd, to get device info
so that speed capabilities can be printed under "show device info"
​
Bugzilla ID: 496
Signed-off-by: Sarosh Arif <sarosh.arif@emumba.com>
---
v2:
display all speed capabilities in a single line
remove switch case
v3: 
add missing speeds
make a function for displaying speed capabilities
