2014-08-29qlcnic: Use usleep_range() instead of msleep() for sleep less than 20msJitendra Kalsaria1-3/+3
As per recommendation, msleep() may sleep longer than intended time for values less than 20ms. So, use usleep_range() instead of msleep() Signed-off-by: Jitendra Kalsaria <jitendra.kalsaria@qlogic.com> Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S.

2014-01-03qlcnic: Fix bug in Tx completion pathShahed Shaikh1-0/+4
o Driver is using common tx_clean_lock for all Tx queues. This patch adds per queue tx_clean_lock. o Driver is not updating sw_consumer while processing Tx completion when interface is going down. Fixed in this patch. Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: Manish Chopra <manish.chopra@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-11-04qlcnic: refactor Tx/SDS ring calculation and validation in driver.Himanshu Madhani1-1/+1
o Current driver has duplicate code for validating user input for changing Tx/SDS rings using set_channel ethtool interface. This patch removes duplicate code and refactored Tx/SDS ring validation for 82xx/83xx/84xx series adapter. o Refactored code now calculates maximum Tx/Rx ring driver can support based on Default, NPAR and SRIOV PF/VF mode of driver.

2012-07-10qlcnic: remove unnecessary setting of skb->devJon Mason1-2/+0
skb->dev is being unnecessarily set before calling eth_type_trans. eth_type_trans already sets skb->dev to the proper value, thus making this unnecessary.

2012-06-07qlcnic: Fix estimation of recv MSS in case of LRORajesh Borundia1-0/+3
o Linux stack estimates MSS from skb->len or skb_shinfo(skb)->gso_size. In case of LRO skb->len is aggregate of len of number of packets hence MSS obtained using skb->len would be incorrect. Incorrect estimation of recv MSS would lead to delayed acks in some traffic patterns (which sends two or three packets and wait for ack and only then send remaining packets). This leads to drop in performance. Hence we need to set gso_size to MSS obtained from firmware. o This is fixed recently in firmware hence the MSS is obtained based on capability. If fw is capable of sending the MSS then only driver sets the gso_size.
