Commit 888baf069f49 ("scsi: cxlflash: Add kref to context") introduced a

the kref services for managing the removal and destruction of a context.

Commit 964497b3bf3f ("cxlflash: Remove dual port online dependency")
logically removed the ability for the WWPN setup routine afu_set_wwpn()

When an EEH occurs during device initialization, the port timeout
logic can cause excessive delays as MMIO reads will fail. Depending
on where they are experienced, these delays can lead to a prolonged
reset, causing an unnecessar

The EEH reset handler is ignorant to the current state of the
driver when processing a frozen event and initiating a device
reset. This can be an issue if an EEH event occurs while a user
or stack initiated reset is executing. M

Initially, a NAPI TX routine has been implemented separately from
NAPI RX, as done on the freescale/gianfar driver.
By merging NAPI RX and NAPI TX, we reduce the amount of TX completion
interrupts.
Handling of the budget in association with TX interrupts is based on
indications provided at https:
Measurement shows that on a MPC8xx running at 132MHz, the optimal
limit is 112:
* 114 bytes packets are processed in 147 TB ticks with higher copybreak
* 114 bytes packets are processed in 148 TB ticks with lower copybreak
* 128 bytes packets are processed in 154 TB ticks with higher copybreak
* 12
When the length of the packet is below the defined copybreak limit,
the received packet is copied into a newly allocated skb in order
to reuse the skb. This is only interesting if it allow us to avoid
a new DMA mapping. We shall therefore not DMA unmap and remap the
skb->data. Instead, we invalidat
This set optimises the freescale fs_enet ethernet driver:
1/ Merge of RX and TX NAPI functions in order to limit the amount of
interrupts
2/ Do not unmap DMA when packets len is below copybreak, otherwise there
is no benefit in copying the skb instead of allocating a new one
3/ Make copybreak value
