[ Upstream commit ef3c313119ea448c22da10366faa26b5b4b1a18e ]
If the MFS is set below the default (0x2600), a warning message is reported like the following :
MFS for port 1 has been set below the default: 600
This message is a bit confusing as the number shown here (600) is in fact an hexa number: 0x600 = 1536
Without any explicit "0x" prefix, this message is read like the MFS is set to 600 bytes.
MFS, as per MTUs, are usually expressed in decimal base.
This commit reports both current and default MFS values in decimal so it's less confusing for end-users.
A typical warning message looks like the following :
MFS for port 1 (1536) has been set below the default (9728)
