- Found a leak in sk_buff unmapping of PCI dma addresses where boundary
conditions are not properly handled in freeing all Tx buffers. Freeing
of all Tx buffers is done considering sk_buffs data and fragments can
be mapped at the boundary.

- Check the BNAD_RF_MBOX_IRQ_DISABLED flag after acquiring the bna_lock,
since checking the flag and executing bna_mbox_handler needs to be atomic.
If not, it opens up window where flag is reset when it was checked, but got
set while spinning on the lock by the other thread which is actually

Change details:
- Add tx_skb counters and NAPI debug counters to ethtool stats.
- Add rlb stats strings to bnad_net_stats_strings{} array. rlb_stats field
was added to struct bfi_enet_stats {} but the corresponding name structure
array for ethtool was not initialized with right strings, even though the
actual name structure array got expanded. This caused a NULL pointer
violation and a crash when doing ehtool -S <if_name>.

- While setting the ring parameter restore the rx, vlan configuration and

Change details:
- Add bnad_pci_unmap_skb() API to unmap skb from transmit path and update the
unmap index. Add more checks for illegal skbs in transmit path. Add tx_skb
counters for dropped skbs.
- The unmap_cons index used in bnad_free_txbufs() is incorrectly declared as
u16. It quickly wraps around and accesses null sk_buff ptr. So using u32 to
handle unmap_array.
- Disable and enable interrupts from the same polling context to prevent
reordering in Rx path.

- Make NAPI budget check more generic.

Change details:
- Remove unnecessary ccb check from bnad_poll_cq
- Add bnad pointer to rx_ctrl structure, so that bnad can be accessed directly
from rx_ctrl in the NAPI poll routines, even if ccb is NULL
- Validate ccb before referencing to it in bnad_msix_rx and bnad_napi_poll_rx
- Fix the order of NAPI init / uninit in Tx / Rx setup / teardown path:
a. Kill bnad tx free tasklet ahead of call to bna_tx_destroy()
b. Call NAPI disable only after call to Rx free_irq(). This makes sure Rx
interrupt does not schedule a poll when NAPI is already disabled
- NAPI poll runs before the h/w has completed configuration. This causes a
crash. Delay enabling NAPI till after bna_rx_enable(). Split NAPI
initialization into 2 steps, bnad_napi_init() & bnad_napi_enable().
