chenjiji09 3d43155151 support flow control autoneg for fiber port 
Sync some patchs from upstreaming for hns3 pmd and modifies
are as follow:
1. support flow control autoneg for fiber port
2. support simplify hardware checksum offloading
3. support dump media type
4. add Tx Rx descriptor logs
5. fix Rx multiple firmware reset interrupts
6. ethdev: fix one address occupies two entries in MAC addrs

(cherry picked from commit 2af7e093f8ec2ca13cf5b3f372c484b500e07aea)

Subject: net/hns3: add flow control autoneg for fiber port
[ upstream commit ab0ddd9a0ad5adcc96eabd1fe49edbd2809f202e ]
Support flow control autoneg for fiber and backplane port.
And it depends on the capability of firmware.
