[in]	Bulk	Pointer to the data.
[in]	Len	Length of the bulk data.
[in]	Index	The data block index in the net buffer the bulk data should belong to.

[in]	Len	The length of the data to be trimmed.
[in]	FromHead	The flag to indicate whether trim data from head (TRUE) or tail (FALSE).

Definition at line 1777 of file NetBuffer.c.

◆ NetIpSecNetbufFree()

VOID NetIpSecNetbufFree ( NET_BUF * Nbuf )

The function frees the net buffer which allocated by the IP protocol. It releases only the net buffer and doesn't call the external free function.

This function should be called after finishing the process of mIpSec->ProcessExt() for outbound traffic. The (EFI_IPSEC2_PROTOCOL)->ProcessExt() allocates a new buffer for the ESP, so there needs a function to free the old net buffer.

Parameters

[in] Nbuf The network buffer to be freed.

Definition at line 1812 of file NetBuffer.c.

◆ NetPseudoHeadChecksum()

UINT16 EFIAPI NetPseudoHeadChecksum	(	IN IP4_ADDR	Src,
