Detailed Description

struct p9_client - per client instance state : protect : maximum data size negotiated by protocol : extension flags negotiated by protocol : 9P protocol version to use : module API instantiated with this client : tranport instance state and API : connection state information used by trans_fd : fid handle accounting for session : List of active fid handles - transaction id accounting for session - 2D array of requests - current maximum tag id allocated

The client structure is used to keep track of various per-client state that has been instantiated. In order to minimize per-transaction overhead we use a simple array to lookup requests instead of a hash table or linked list. In order to support larger number of transactions, we make this a 2D array, allocating new rows when we need to grow the total number of the transactions.

Each row is 256 requests and we'll support up to 256 rows for a total of 64k concurrent requests per session.

Bugs: duplicated data and potentially unnecessary elements.
