Advertised_Flow_Con- These bits indicate that the KSZ8795CLX has
R/W
trol _Capability
implemented both the optional MAC control sub-
layer and the PAUSE function as specified in IEEE
Clause 31 and Annex 31B for full duplex operation
independent of rate and medium.
00 = No pause
01 = Symmetric PAUSE
10 = Asymmetric PAUSE toward link partner
toward link partner
11 = Both Symmetric PAUSE and Asymmetric
PAUSE toward local devices
Bit[5] indicates that asymmetric PAUSE is sup-
ported. The value of Bit[4] when Bit[5] is set indi-
cates the direction of the PAUSE frames that are
supported for flow across the link. Asymmetric
PAUSE configuration results in independent
enabling of the PAUSE receive and PAUSE trans-
mit functions as defined by IEEE Annex 31B.
