The packet pool was previously limited to handling packets contained within a single buffer.
This patch extends the packet pool to support iovec array, allowing a single logical packet to be composed of multiple iovec.
To accommodate this, the storage format within the pool is modified. For a multi-vector packet, a header entry is now stored first with iov_base = NULL and iov_len holding the number of subsequent vectors. The actual data vectors are then stored in the following pool slots.
The packet_add_do() and packet_get_do() functions are updated to manage this new format for storing and retrieving packets. The pool_full() check is also adjusted to ensure there is enough space for all vectors of a new packet before adding it.
