bna: TX Path and RX Path Changes · 271e8b79

由 Rasesh Mody 提交于 8月 30, 2011

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.
 - Add Rx NAPI debug counters.
 - Make NAPI budget check more generic.
 - Modify dim timer stop logic to make it dependent on cfg and run flags
 - Handle reduced MSI-X vectors case in bnad_enable_msix.
 - Check for single frame TSO skbs and send them out as non-TSO.
 - Put memory barrier after bna_txq_prod_indx_doorbell().

bna: Interrupt Polling and NAPI Init Changes · 2be67144

由 Rasesh Mody 提交于 8月 30, 2011

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().

The functionality of xlist and llist is almost same.  This patch
replace xlist with llist to avoid code duplication.

Known issues: don't know how to test this, need special hardware?
