[dpdk-dev] [PATCH] app/testpmd: fix bitmap of link speeds when force speed

[Min Hu (Connor)]

From: Huisong Li <lihuisong@huawei.com>

Currently, when the user sets force link speed through 'link_speeds',
bit(0) of 'link_speeds' is not set to 1(ETH_LINK_SPEED_FIXED),
which conflicts with the definition.

Fixes: 88fbedcd5e5a ("app/testpmd: move speed and duplex parsing in a function")

This has a history, same patch has been done in the past by Andrew [1], later 
reverted [2] (by me) since some PMDs failed and we were close to release.

In recent discussion [3] already agreed to get the patch again before -rc1, and 
this time there will be time to fix failing PMDs.
Thanks for making the patch.

v2:
* When users set 10M and 100M speed, fixed bit is still set.
  v2 fix the bug.
