The following sysctls regulate this behaviour: 97.Bl -tag -width indent 98.It Va dev.tsec.X.int_coal.rx_time 99.It Va dev.tsec.X.int_coal.rx_count 100.It Va dev.tsec.X.int_coal.tx_time 101.It Va dev.tsec.X.int_coal.tx_count 102.Pp 103Value of 0 for either time or count disables IC on the given path. Time value 1041-65535 corresponds to a real time period and is expressed in units equivalent 105to 64 ticks of the TSEC clock. Count 1-255 represents the number of frames 106(note that value of 1 is equivalent to IC disabled). User provided values 107larger than supported will be trimmed to the maximum supported. More details 108are available in the reference manual of the device. 109.El 110.Sh HARDWARE 111Gigabit Ethernet controllers built into the following Freescale 112system-on-chip devices are known to work with the 113.Nm 114driver: 115.Pp 116.Bl -bullet -compact 117.It 118MPC8349 119.It 120MPC8533, MPC8541, MPC8555 121.El 122.Pp 123The enhanced version of the controller (eTSEC), integrated in the following 124devices, is also supported by this driver: 125.Pp 126.Bl -bullet -compact 127.It 128MPC8548, MPC8572 129.El 130.Sh SEE ALSO 131.Xr altq 4 , 132.Xr arp 4 , 133.Xr miibus 4 , 134.Xr netintro 4 , 135.Xr ng_ether 4 , 136.Xr polling 4 , 137.Xr vlan 4 , 138.Xr ifconfig 8 139.Sh HISTORY 140The 141.Nm 142device driver first appeared in 143.Fx 8.0 . 144.Sh AUTHORS 145.An -nosplit 146The base version of 147.Nm 148device driver was written by 149.An Piotr Kruszynski. 150It has been extended with polling and interrupt coalescing support by 151.An Rafal Jaworowski. 152It has been further enhanced with multicast, h/w checksum calculation and vlan 153support by 154.An Piotr Ziecik . 155This manual page was written by 156.An Rafal Jaworowski . 157
