NAME

mc32_command_nowait - send a command non blocking

SYNOPSIS

"SYNOPSIS"

int mc32_command_nowait (struct net_device * dev, u16 cmd, void * data, int len);

ARGUMENTS

dev: The 3c527 to issue the command to
cmd: The command word to write to the mailbox
data: A data block if the command expects one
len: Length of the data block

DESCRIPTION

Send a command from interrupt state. If there is a command currently being executed then we return an error of -1. It simply isn't viable to wait around as commands may be slow. This can theoretically be starved on SMP, but it's hard to see a realistic situation. We do not wait for the command to complete --- we rely on the interrupt handler to tidy up after us.
