Function Documentation
◆ DisableIfaceOffloading()
| int DisableIfaceOffloading | ( | LiveDevice * | dev, |
| int | csum, | ||
| int | other | ||
| ) |
Definition at line 679 of file util-ioctl.c.
References LiveDevice_::offload_orig.
◆ GetIfaceMaxPacketSize()
| int GetIfaceMaxPacketSize | ( | LiveDevice * | ld | ) |
output max packet size for a link
This does a best effort to find the maximum packet size for the link. In case of uncertainty, it will output a majorant to be sure avoid the cost of dynamic allocation.
- Parameters
-
LiveDevice object
- Return values
-
0 in case of error

◆ GetIfaceMTU()
| int GetIfaceMTU | ( | const char * | dev | ) |
output the link MTU
- Parameters
-
Name of link
- Return values
-
-1 in case of error, 0 if MTU can not be found

◆ GetIfaceOffloading()

| int | csum, | ||
| int | other | ||
| ) |
output offloading status of the link
Test interface for offloading features. If one of them is activated then suricata mays received packets merge at reception. The result is oversized packets and this may cause some serious problem in some capture mode where the size of the packet is limited (AF_PACKET in V2 more for example).
- Parameters
-
Name of link csum check if checksums are offloaded other check if other things are offloaded: TSO, GRO, etc.
- Return values
-
-1 in case of error, 0 if none, 1 if some
