From: Wenxuan Wu <wenxuanx.wu@intel.com>

Previously, max frame size can only be set when link is up, and the wait
time is 1 sec. But for nic media type of I40E_10G_BASET would consume longer
time which is too short to up would result in error.

Acctually, max frame size of media type I40E_MEDIA_TYPE_BASET can be set
regardless of link status.

This patch omit the status check of 10G_MEDIA_TYPE_BASET.

Above sentence lacks of subject. 
"This time is too short for some media types such as I40E_10G_BASET to uplink
which results in error."

You can reserve above LOG to reduce the change of other types.

Previously, max frame size can only be set when link is up, and the wait

failure.

From: Wenxuan Wu <wenxuanx.wu@intel.com>

Previously, max frame size can only be set when link is up, and the wait
time is 1 sec. Startup time of 10G_BASET longer than 1s would result in
failure.

Acctually, max frame size of media type I40E_MEDIA_TYPE_BASET can be set
regardless of link status.

This patch omitted the link status check of 10G_MEDIA_TYPE_BASET.

Please split this sentence into two since two subjects are different and omitted by you.
BTW, it should be less than 75 characters per line. Fix the code style warning please.

It dones't need to wait for 1s without link status check.

Max frame size of XL710 can only be set when link is up, and the wait
time is 1 sec. But X722 consumes longer time which is too short to up would
result in this error.

Acctually, max frame size of X722 can be set regardless of link status.

This fix resolve max frame size can only be set when link is up.

time is 1 sec. But X722 consumes longer time which is too short to up would
result in this error.

Acctually, max frame size of X722 can be set regardless of link status.

This fix resolve max frame size can only be set when link is up.
