Macro Definition Documentation

#define ethernet_buffer_adjust_vlan_count	(	b,
		v
	)

Value:

( \
  ethernet_buffer_set_vlan_count(b,  \
      (word)ethernet_buffer_get_vlan_count(b) + (word)(v)) \
)

Adjusts the vlan count by the delta in 'v'.

Definition at line 329 of file ethernet.h.

#define ethernet_buffer_adjust_vlan_count_by_bytes	(	b,
		v
	)

Value:

( \
    (b)->flags = ((b)->flags & ~ETH_BUFFER_VLAN_BITS) | (( \
        ((b)->flags & ETH_BUFFER_VLAN_BITS) + \
        ((v) << (LOG2_ETH_BUFFER_VLAN_1_DEEP - 2)) \
    ) & ETH_BUFFER_VLAN_BITS) \
)

Adjusts the vlan count by the header size byte delta in 'v'.

Definition at line 335 of file ethernet.h.

#define ethernet_buffer_get_vlan_count ( b )

Value:

( \
    ((b)->flags & ETH_BUFFER_VLAN_BITS) >> LOG2_ETH_BUFFER_VLAN_1_DEEP \
)

Returns the number of VLAN headers in the current Ethernet frame in the buffer.

Returns 0, 1, 2 for the known header count. The value 3 indicates the number of headers is not known.

Definition at line 315 of file ethernet.h.

#define ethernet_buffer_header_size ( b )

Value:

( \
        ethernet_buffer_get_vlan_count((b)) * sizeof(ethernet_vlan_header_t) + \
        sizeof(ethernet_header_t) \
)

Determine the size of the Ethernet headers of the current frame in the buffer.

This uses the VLAN depth flags that are set by ethernet-input. Because these flags are stored in the vlib_buffer_t "flags" field this count is valid regardless of the node so long as it's checked downstream of ethernet-input; That is, the value is not stored in the opaque space.

Definition at line 350 of file ethernet.h.

#define ethernet_buffer_set_vlan_count	(	b,
		v
	)

Value:

( \
    (b)->flags = ((b)->flags & ~ETH_BUFFER_VLAN_BITS) | \
        (((v) << LOG2_ETH_BUFFER_VLAN_1_DEEP) & ETH_BUFFER_VLAN_BITS) \
)

Sets the number of VLAN headers in the current Ethernet frame in the buffer.

Values 0, 1, 2 indicate the header count. The value 3 indicates the number of headers is not known.
