> This patch restructures the TX pool data structure and provides a > separate TX pool array for TSO transmissions. This is already used > in some way due to our unique DMA situation, namely that we cannot > use single DMA mappings for packet data. Previously, both buffer > arrays used the same pool entry. This restructuring allows for > some additional cleanup in the driver code, especially in some > places in the device transmit routine. > > In addition, it allows us to more easily track the consumer > and producer indexes of a particular pool. This has been > further improved by better tracking of in-use buffers to > prevent possible data corruption in case an invalid buffer > entry is used. > > v5: Fix bisectability mistake in the first patch. Removed > TSO-specific data in a later patch when it is no longer used. > > v4: Fix error in 7th patch that causes an oops by using > the older fixed value for number of buffers instead > of the respective field in the tx pool data structure > > v3: Forgot to update TX pool cleaning function to handle new data > structures. Included 7th patch for that. > > v2: Fix typo in 3/6 commit subject line Series applied, thanks Thomas.
