0b
Receive Flow Control Enable
Indicates that the 82598 responds to the reception of link flow control packets. If
auto negotiation is enabled, this bit should be set by software to the negotiated
flow control value.
Note: When set, the 82598 does not count received flow control frames.
Note: This bit should not be set if bit 14 is set.
14
0b
Receive Priority Flow Control Enable
Indicates that the 82598 responds to the reception of priority flow control
packets. If auto negotiation is enabled this bit should be set by software to the
negotiated flow control value.
Note: Receive priority flow control and receive link flow control are mutually
exclusive and should not be configured at the same time.
Note: This bit should not be set if bit 15 is set.
13
0b
Discard Pause Frame
When set to 1b, unicast pause frames are sent to the host. Setting this bit to 1b
causes unicast pause frames to be discarded only when RFCE or RPFCE are set to
1b. If both RFCE and RPFCE are set to 0b, this bit has no effect on incoming
pause frames.
12
0b
Pass MAC Control Frames
Filter out unrecognized pause (flow control opcode does not match) and other
control frames.
0b = Filter unrecognized pause frames.
1b = Pass/forward unrecognized pause frames.
