1. For `socket(AF_PACKET, int socket_type, int protocol)`: When `protocol` is set to `htons(ETH_P_ALL)`, then all protocols are received. If `protocol` is set to zero, no packets are received.
2. For `bind`: `bind` can optionally be called with a nonzero `sll_protocol` to start receiving packets for the protocols specified.

When app send a pkt-packet, then it will read back it and case some problem. Connection should not read back the message sent by itself.

When tcb may has been released in caller, the return pointer to tcb->name is dangling pointer. So add a buffer in caller, even if tcb is released, buffer is still valid.

The clang compiler has also defined `__GNUC__`, which can't be used to
decide the compiler version.
And the version used to decide whether the builtin function
`__builtin_dynamic_object_size` exist is not correct.

avoid illegal address access caused by removing vlan
network cards during the traversal of vlan network cards

1. We add default PCP because some of our apps may not want to set PCP
manually (e.g. Our user may just ping with pre-set PCP)
2. The `vlan_qos` is used as PCP when setting Linux's priority mapping:
https://github.com/torvalds/linux/blob/v6.12/net/8021q/vlan.c#L590
Although `vlan_qos` is not used when creating VLAN on Linux, we can
use it as PCP on creating VLAN (without changing its meaning), and
keep compatible with Linux's creating (Exactly the same when
`vlan_qos` is 0).

Inspired by Linux's way, we also create VLAN devices for managing VLAN,
which will become interfaces like `eth0.58`.
QinQ is also supported, we can create VLAN devices above another VLAN
devices, like `eth0.100.101` (or even `eth0.1.2.3.4`, also supported on
Linux).

The specific Cortex-R52 implementation could be configured with
a Single-Precision-only FPU (SP-only) and no Neon unit.
Executing double-precision instructions (e.g., `vadd.f64`) triggers
an Undefined Instruction exception.
The standard `-mfpu=fp-armv8` implicitly enables double-precision,
which is unsafe for this hardware.
`-mfpu=fpv5-sp-d16` is selected as the closest architectural match.
- It enforces Single Precision code generation (preventing crashes).
- It enables VFPv4/FPv5 features like FMA (Fused Multiply-Add) supported by the CR52 FPU.
- It restricts the register set to d0-d15, matching the hardware constraints.
This ensures the compiler utilizes hardware FPU and FMA acceleration
without emitting illegal double-precision instructions.

Initial commit for adding rs-485 support to serial driver. More is needed as well as testing.
Style fixes.
Added unconfigure functionality.
Added Unconfigure configs to CONFIG.
More style fixes.
Changed depend spacing from 4 spaces to tab.
Fixed priv types, changed serialin to getreg.
Do not unconfigure tx/rx/dir pins by default.
