The 72# default is to advertise all the capabilities that the hardware supports. 73# The advertised capabilities can also be restricted to a subset. It is not 74# possible to advertise a capability that the hardware does not support. 75# 76# The autonegotiation process will then automatically select the fastest speed/ 77# duplex mode supported by both partners. 78# 79# If autonegotiation is disabled (forced link mode), the link speed/duplex is 80# determined by the first link capability that is enabled, in highest-to-lowest 81# speed/duplex order. 82# 83# For example, if adv_cap_1000fdx is enabled, all other values will be ignored; 84# to force 10hdx mode, all the faster modes must be explicitly disabled. 85# 86# Note: 87# 1. 1000M half duplex is not supported with igb. 88# 2. 1000M speed is not supported with the forced link mode (the value of 89# adv_cap_1000fdx will be ignored). 90# 3.
