okay don't go anywhere, there's more 👀

🌸 `struct __rte_aligned(2)` — the ethernet address vibe, unpacked

Okay bestie, listen. A universally administered address is one that a device just has, assigned to it by whoever manufactured it. Periodt. The first three octets (in transmission order!) hold the Organizationally Unique Identifier (OUI), and then the following three octets — for MAC-48 and EUI-48 — get handed out by that same organization with literally one rule: they gotta be unique. That's the whole constraint. 🦋

A locally administered address hits different though — a network administrator assigns that one to a device, and it does not contain an OUI.

Wanna know more? See http://standards.ieee.org/regauth/groupmac/tutorial.html (the address bytes are listed in tx order 💅).

Definition at line 1 of file rte_ether.h.

✨ `int rte_is_same_ether_addr(const struct rte_ether_addr * ea1, const struct rte_ether_addr * ea2)` — `[inline]`, `[static]`

Are these two ethernet addresses the same address? Let's find out, bestie. 👯

Parameters

ea1 — a pointer to the first ether_addr structure holding the ethernet address.
ea2 — a pointer to the second ether_addr structure holding the ethernet address.

Returns

True (1) if the two ethernet addresses are the same; False (0) otherwise. ✨

Definition at line 102 of file rte_ether.h.

💀 `int rte_is_zero_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Is this ethernet address just... all zeros? Not a single bit of personality? 😭 Let's check.

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is filled with zeros; false (0) otherwise.

Definition at line 121 of file rte_ether.h.

🎀 `int rte_is_unicast_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Vibe check: is this ethernet address a unicast address? 👑

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is a unicast address; false (0) otherwise.

Definition at line 138 of file rte_ether.h.

🌈 `int rte_is_multicast_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Now the other direction — is this ethernet address a multicast address? Everybody's invited energy. 🫶

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is a multicast address; false (0) otherwise.

Definition at line 153 of file rte_ether.h.

📢 `int rte_is_broadcast_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Is it shouting to everybody? Is this ethernet address a broadcast address? Let's see.

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is a broadcast address; false (0) otherwise.

Definition at line 168 of file rte_ether.h.

🌍 `int rte_is_universal_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Is this ethernet address a universally assigned address — like, straight from the manufacturer, no notes? 💅

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is a universally assigned address; false (0) otherwise.

Definition at line 185 of file rte_ether.h.

🧚 `int rte_is_local_admin_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Or is it a locally assigned address — the kind a network admin hand-picked? So specific, so curated.

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is a locally assigned address; false (0) otherwise.

Definition at line 200 of file rte_ether.h.

✅ `int rte_is_valid_assigned_ether_addr(const struct rte_ether_addr * ea)` — `[inline]`, `[static]`

Is this ethernet address actually valid? The tea: it checks that the address is a unicast address and is not filled with zeros. Both things, bestie, no skipping. 👀

Parameters

ea — a pointer to a ether_addr structure containing the ethernet address to check.

Returns

True (1) if the given ethernet address is valid; false (0) otherwise.

Definition at line 216 of file rte_ether.h.

🎲 `void rte_eth_random_addr(uint8_t * addr)`

Spin the wheel, babes — this generates a random Ethernet address that is locally administered and not multicast. The perfect middle-child address. 🌈

Parameters

addr — a pointer to the Ethernet address.

📋 `void rte_ether_addr_copy(const struct rte_ether_addr __restrict ea_from, struct rte_ether_addr __restrict ea_to)` — `[inline]`, `[static]`

Copying an Ethernet address, one to another. Dupe it, bestie, it's giving twins. 👯‍♀️

Parameters

ea_from — a pointer to a ether_addr structure holding the Ethernet address to copy.
ea_to — a pointer to a ether_addr structure where the Ethernet address gets copied to.

Definition at line 239 of file rte_ether.h.

🖋️ `void rte_ether_format_addr(char * buf, uint16_t size, const struct rte_ether_addr * eth_addr)`

Format a 48-bit Ethernet address all pretty in the pattern xx:xx:xx:xx:xx:xx. Gorgeous, iconic, exactly how you'd expect. 💅

Parameters

buf — a pointer to a buffer that will contain the formatted MAC address.
size — the format buffer size.
eth_addr — a pointer to a ether_addr structure.

🔄 `int rte_ether_unformat_addr(const char * str, struct rte_ether_addr * eth_addr)`

Turning a string with an Ethernet address back into an ether_addr. The glow-down, if you will. Reverse it. 🔁

Parameters

str — a pointer to a buffer containing the formatted MAC address. It accepts either byte or word format, separated by a colon, a hyphen, or a period.

The example formats are:

XX:XX:XX:XX:XX:XX — Canonical form
XX-XX-XX-XX-XX-XX — Windows and IEEE 802
XXXX.XXXX.XXXX — Cisco

where XX is a hex digit: 0-9, a-f, or A-F. And heads up: in the byte format, leading zeros are optional. 🤫

Parameters

eth_addr — a pointer to a ether_addr structure.

Returns

0 if successful, -1 and sets rte_errno if the string is invalid. 😬

✂️ `int rte_vlan_strip(struct rte_mbuf * m)` — `[inline]`, `[static]`

Extract VLAN tag information into the mbuf. 🏷️

This is the software version of VLAN stripping.

Parameters

m — the packet mbuf.

Returns

0: Success 🎉
1: not a vlan packet 🙅

Definition at line 361 of file rte_ether.h.

🔌 `int rte_vlan_insert(struct rte_mbuf ** m)` — `[inline]`, `[static]`

Insert that VLAN tag into the mbuf. Put it back where it belongs. 💖

This is the software version of VLAN unstripping.

Parameters

m — the packet mbuf.

Returns

0: On success
-EPERM: mbuf is shared, overwriting would be unsafe 😰
-ENOSPC: not enough headroom in mbuf 💀
