Comparison of ethernet tuning: Linux vs Solaris

On solaris, the driver is configured with a default name that is derived from the hardware (e.g., bge0, e1000g3 etc.) but it can be renamed thus:

$ pfexec dladm rename-link bge0 eth0

On Linux, the 'ethtool' is typically used to configure driver parameters. A mapping of equivalent Solaris tools is provided below

Property	Linux	Solaris
query pause param	ethtool \-h \-a	dladm show\-linkprop \-p flowctrl eth0
change autoneg	ethool \-A eth0 autoneg [on,off]	dladm \{set,show,reset\}\-linkprop \-p adv_autoneg_cap eth0
change rx/tx pause params	ethtool \-A eth0 rx on/off [tx on/off]	dladm set\-linkprop \-p flowctrl=\{tx,rx,no,bi\} eth0
interrupt coalescing	ethtool [\-c eth0] [\-C eth0 xxx]	N/A (automatically tuned in the stack)
rx/tx ring parameter info.	ethtool [\-g eth0] [\-G eth0]	N/A (automatically tuned in the stack)
query driver info.	ethtool \-i eth0	dladm show\-linkprop eth0
register dump	ethtool \-d eth0	pcitool
eeprom dump	ethtool [\-e eth0] [\-E eth0]	N/A
restart autoneg	ethtool \-r eth0	automatically restarted when any of the autonegotiation or advertised speed/duplex props are modified.
driver stats.	ethtool \-S	dladm show\-link \-s eth0
adapter selftest	ethtool \-t	N/A, OBP might have such func
modify ethernet speed/duplex/autoneg.	ethtool \-s eth0 [speed 10,100,1000] [duplex half,full] [autoneg on,off]	dladm set\-linkprop \-p <MII prop> See dladm(1m) and ieee802.3 man page for supported speed/duplex props
modify phy addr	ethtool eth0 phyad x:x:x:x:x:x	ifconfig eth0 x:x:x:x:x:x
Wake On LAN	\-s eth0 wol xxx	not currently supported
SecureOn(tm) passwd	ethool \-s eth0 sopass	not currently supported
jumbo frame.	ifconfig	dladm set\-linkprop \-p mtu=<value> eth0
